+ * @property {number} code
+ * Error code - {@link errors.queryResultErrorCode queryResultErrorCode} value.
+ *
+ * @property {string} query

+     * - If you alter the size of `data` directly or through the `result` object, it may affect `QueryResultMask`
+     *   validation for regular queries, which is executed right after.
+     * - Any data pre-processing needs to be fast here, to avoid performance penalties.
+     * - If the event handler throws an error, the original request will be rejected with that error.

+     * For methods {@link Database#multi Database.multi} and {@link Database#multiResult Database.multiResult},

+     *
+     * @param {Array<Object>} data
+     * Array of received objects/rows.
+     *
+     * If any of those objects are modified during notification, the client will receive the modified data.
+     *
+     * @param {external:Result} result
+     * - Original $[Result] object, if the data is from a non-stream query, in which case `data = result.rows`.
+     *   For single-query requests, $[Result] object is extended with property `duration` - number of milliseconds
+     *   it took to send the query, execute it and get the result back.
+     * - It is `undefined` when the data comes from a stream (method {@link Database#stream Database.stream}).

+ *
+ * @property {string|object} cn
+ *
+ * Set only for event {@link event:error error}, and only when the error is connection-related.
+ *
+ * It is a safe copy of the connection string/object that was used when initializing `db` - the database instance.
+ *
+ * If the original connection contains a password, the safe copy contains it masked with symbol `#`, so the connection
+ * can be logged safely, without exposing the password.
+ *
+ * @property {*} dc
+ * Database Context that was used when creating the database object (see {@link Database}). It is set for all events.
+ *
+ * @property {string|object} query
+ *
+ * Query string/object that was passed into the query method. This property is only set during events {@link event:query query},
+ * {@link event:receive receive} and {@link event:error error} (only when the error is query-related).
+ *
+ * @property {external:Client} client
+ *
+ * $[pg.Client] object that represents the connection. It is set for all events, except for event {@link event:error error}
+ * when it is connection-related. Note that sometimes the value may be unset when the connection is lost.
+ *
+ * @property {*} params - Formatting parameters for the query.
+ *
+ * It is set only for events {@link event:query query}, {@link event:receive receive} and {@link event:error error}, and only
+ * when it is needed for logging. This library takes an extra step in figuring out when formatting parameters are of any value
+ * to the event logging:
+ * - when an error occurs related to the query formatting, event {@link event:error error} is sent with the property set.
+ * - when initialization parameter `pgFormat` is used, and all query formatting is done within the $[PG] library, events
+ * {@link event:query query} and {@link event:receive receive} will have this property set also, since this library no longer
+ * handles the query formatting.
+ *
+ * When this parameter is not set, it means one of the two things:
+ * - there were no parameters passed into the query method;
+ * - property `query` of this object already contains all the formatting values in it, so logging only the query is sufficient.
+ *
+ * @property {TaskContext} ctx
+ * _Task/Transaction Context_ object.
+ *
+ * This property is always set for events {@link event:task task} and {@link event:transact transact}, while for events
+ * {@link event:query query}, {@link event:receive receive} and {@link event:error error} it is only set when they occur
+ * inside a task or transaction.

+ * @description
+ * Performance-optimized, read-only structure with query-formatting columns.
+ *
+ * In order to avail from performance optimization provided by this class, it should be created
+ * only once, statically, and then reused.
+ *
+ * @param {object|helpers.Column|array} columns
+ * Columns information object, depending on the type:
+ *
+ * - When it is a simple object, its properties are enumerated to represent both column names and property names
+ *   within the source objects. See also option `inherit` that's applicable in this case.
+ *
+ * - When it is a single {@link helpers.Column Column} object, property {@link helpers.ColumnSet#columns columns} is initialized with
+ *   just a single column. It is not a unique situation when only a single column is required for an update operation.
+ *
+ * - When it is an array, each element is assumed to represent details for a column. If the element is already of type {@link helpers.Column Column},
+ *   it is used directly; otherwise the element is passed into {@link helpers.Column Column} constructor for initialization.
+ *   On any duplicate column name (case-sensitive) it will throw {@link external:Error Error} = `Duplicate column name "name".`
+ *
+ * - When it is none of the above, it will throw {@link external:TypeError TypeError} = `Invalid parameter 'columns' specified.`
+ *
+ * @param {object} [options]
+ *
+ * @param {helpers.TableName|string|{table,schema}} [options.table]
+ * Table details.
+ *
+ * When it is a non-null value, and not a {@link helpers.TableName TableName} object, a new {@link helpers.TableName TableName} is constructed from the value.
+ *
+ * It can be used as the default for methods {@link helpers.insert insert} and {@link helpers.update update} when their parameter
+ * `table` is omitted, and for logging purposes.
+ *
+ * @param {boolean} [options.inherit = false]
+ * Use inherited properties in addition to the object's own properties.
+ *
+ * By default, only the object's own properties are enumerated for column names.
+ *
+ * @returns {helpers.ColumnSet}

+ * The class parses details into a template, to be used for query generation.
+ *
+ * @param {string|helpers.ColumnConfig} col
+ * Column details, depending on the type.
+ *
+ * When it is a string, it is expected to contain a name for both the column and the source property, assuming that the two are the same.
+ * The name must adhere to JavaScript syntax for variable names. The name can be appended with any format modifier as supported by
+ * {@link formatting.format as.format} (`^`, `~`, `#`, `:csv`, `:list`, `:json`, `:alias`, `:name`, `:raw`, `:value`), which is then removed from the name and put
+ * into property `mod`. If the name starts with `?`, it is removed, while setting flag `cnd` = `true`.
+ *
+ * If the string doesn't adhere to the above requirements, the method will throw {@link external:TypeError TypeError} = `Invalid column syntax`.
+ *
+ * When `col` is a simple {@link helpers.ColumnConfig ColumnConfig}-like object, it is used as an input configurator to set all the properties
+ * of the class.
+ *
+ * @property {string} name
+ * Destination column name + source property name (if `prop` is skipped). The name must adhere to JavaScript syntax for variables,
+ * unless `prop` is specified, in which case `name` represents only the column name, and therefore can be any non-empty string.
+ *
+ * @property {string} [prop]
+ * Source property name, if different from the column's name. It must adhere to JavaScript syntax for variables.
+ *
+ * It is ignored when it is the same as `name`.
+ *
+ * @property {string} [mod]
+ * Formatting modifier, as supported by method {@link formatting.format as.format}: `^`, `~`, `#`, `:csv`, `:list`, `:json`, `:alias`, `:name`, `:raw`, `:value`.
+ *
+ * @property {string} [cast]
+ * Server-side type casting, without `::` in front.
+ *
+ * @property {boolean} [cnd]
+ * Conditional column flag.
+ *
+ * Used by methods {@link helpers.update update} and {@link helpers.sets sets}, ignored by methods {@link helpers.insert insert} and
+ * {@link helpers.values values}. It indicates that the column is reserved for a `WHERE` condition, not to be set or updated.
+ *
+ * It can be set from a string initialization, by adding `?` in front of the name.
+ *
+ * @property {*} [def]
+ * Default value for the property, to be used only when the source object doesn't have the property.
+ * It is ignored when property `init` is set.
+ *
+ * @property {helpers.initCB} [init]
+ * Override callback for the value.
+ *
+ * @property {helpers.skipCB} [skip]
+ * An override for skipping columns dynamically.
+ *
+ * Used by methods {@link helpers.update update} (for a single object) and {@link helpers.sets sets}, ignored by methods

+ * @method helpers.update
+ * @description
+ * Generates a simplified `UPDATE` query for either one object or an array of objects.
+ *
+ * The resulting query needs a `WHERE` clause to be appended to it, to specify the update logic.
+ * This is to allow for update conditions of any complexity that are easy to add.
+ *
+ * @param {object|object[]} data
+ * An update object with properties for update values, or an array of such objects.
+ *
+ * When `data` is not a non-null object and not an array, it will throw {@link external:TypeError TypeError} = `Invalid parameter 'data' specified.`
+ *
+ * When `data` is an empty array, it will throw {@link external:TypeError TypeError} = `Cannot generate an UPDATE from an empty array.`
+ *
+ * When `data` is an array that contains a non-object value, the method will throw {@link external:Error Error} =
+ * `Invalid update object at index N.`
+ *
+ * @param {array|helpers.Column|helpers.ColumnSet} [columns]
+ * Set of columns to be updated.
+ *
+ * It is optional when `data` is a single object, and required when `data` is an array of objects. If not specified for an array
+ * of objects, the method will throw {@link external:TypeError TypeError} = `Parameter 'columns' is required when updating multiple records.`
+ *
+ * When `columns` is not a {@link helpers.ColumnSet ColumnSet} object, a temporary {@link helpers.ColumnSet ColumnSet}
+ * is created - from the value of `columns` (if it was specified), or from the value of `data` (if it is not an array).
+ *
+ * When the final {@link helpers.ColumnSet ColumnSet} is empty (no columns in it), the method will throw
+ * {@link external:Error Error} = `Cannot generate an UPDATE without any columns.`, unless option `emptyUpdate` was specified.
+ *
+ * @param {helpers.TableName|string|{table,schema}} [table]
+ * Table to be updated.
+ *
+ * It is normally a required parameter. But when `columns` is passed in as a {@link helpers.ColumnSet ColumnSet} object
+ * with `table` set in it, that will be used when this parameter isn't specified. When neither is available, the method
+ * will throw {@link external:Error Error} = `Table name is unknown.`
+ *
+ * @param {{}} [options]
+ * An object with formatting options for multi-row `UPDATE` queries.
+ *
+ * @param {string} [options.tableAlias=t]
+ * Name of the SQL variable that represents the destination table.
+ *
+ * @param {string} [options.valueAlias=v]
+ * Name of the SQL variable that represents the values.
+ *
+ * @param {*} [options.emptyUpdate]
+ * This is a convenience option, to avoid throwing an error when generating a conditional update results in no columns.
+ *
+ * When present, regardless of the value, this option overrides the method's behavior when applying `skip` logic results in no columns,
+ * i.e. when every column is being skipped.
+ *
+ * By default, in that situation the method throws {@link external:Error Error} = `Cannot generate an UPDATE without any columns.`
+ * But when this option is present, the method will instead return whatever value the option was passed.
+ *
+ * @returns {*}
+ * An `UPDATE` query string that needs a `WHERE` condition appended.
+ *
+ * If it results in an empty update, and option `emptyUpdate` was passed in, then the method returns the value
+ * to which the option was set.
+ *
+ * @see
+ *  {@link helpers.Column Column},
+ *  {@link helpers.ColumnSet ColumnSet},
+ *  {@link helpers.TableName TableName}
+ *
+ * @example
+ *
+ * const pgp = require('pg-promise')({
+ *    capSQL: true // if you want all generated SQL capitalized
+ * });
+ *
+ * const dataSingle = {id: 1, val: 123, msg: 'hello'};
+ * const dataMulti = [{id: 1, val: 123, msg: 'hello'}, {id: 2, val: 456, msg: 'world!'}];
+ *
+ * // Although column details can be taken from the data object, it is not
+ * // a likely scenario for an update, unless updating the whole table:
+ *
+ * pgp.helpers.update(dataSingle, null, 'my-table');
+ * //=> UPDATE "my-table" SET "id"=1,"val"=123,"msg"='hello'
+ *
+ * @example
+ *
+ * // A typical single-object update:
+ *
+ * // Dynamic conditions must be escaped/formatted properly:
+ * const condition = pgp.as.format(' WHERE id = ${id}', dataSingle);
+ *
+ * pgp.helpers.update(dataSingle, ['val', 'msg'], 'my-table') + condition;
+ * //=> UPDATE "my-table" SET "val"=123,"msg"='hello' WHERE id = 1
+ *
+ * @example
+ *
+ * // Column details are required for a multi-row `UPDATE`;
+ * // Adding '?' in front of a column name means it is only for a WHERE condition:
+ *
+ * pgp.helpers.update(dataMulti, ['?id', 'val', 'msg'], 'my-table') + ' WHERE v.id = t.id';
+ * //=> UPDATE "my-table" AS t SET "val"=v."val","msg"=v."msg" FROM (VALUES(1,123,'hello'),(2,456,'world!'))
+ * //   AS v("id","val","msg") WHERE v.id = t.id

+ * @author Vitaly Tomilov
+ * @module pg-promise
+ *
+ * @description
+ * ## pg-promise v10.15
+ * All documentation here is for the latest official release only.
+ *
+ * ### Initialization Options
+ *
+ * Below is the complete list of _Initialization Options_ for the library that can be passed in during
+ * the library's initialization:
+ *
+ * ```js
+ * const initOptions = {/* options as documented below */};
+ *
+ * const pgp = require('pg-promise')(initOptions);
+ * ```
+ *
+ * @param {{}} [options]
+ * Library Initialization Options.
+ *
+ * @param {boolean} [options.pgFormatting=false]
+ * Redirects all query formatting to the $[pg] driver.
+ *
+ * By default (`false`), the library uses its own advanced query-formatting engine.
+ * If you set this option to a truthy value, query formatting will be done entirely by the
+ * $[pg] driver, which means you won't be able to use any of the feature-rich query formatting
+ * that this library implements, restricting yourself to the very basic `$1, $2,...` syntax.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {boolean} [options.pgNative=false]
+ * Use $[Native Bindings]. Library $[pg-native] must be included and installed independently, or else there will
+ * be an error thrown: {@link external:Error Error} = `Failed to initialize Native Bindings.`
+ *
+ * This is a static option (can only be set prior to initialization).
+ *
+ * @param {object|function} [options.promiseLib=Promise]
+ * Overrides the default (ES6 Promise) promise library for its internal use.
+ *
+ * Example below sets to use $[Bluebird] - the best and recommended promise library. It is the fastest one,
+ * and supports $[Long Stack Traces], essential for debugging promises.
+ *
+ * ```js
+ * const Promise = require('bluebird');
+ * const initOptions = {
+ *     promiseLib: Promise
+ * };
+ * const pgp = require('pg-promise')(initOptions);
+ * ```
+ *
+ * All existing promise libraries are supported. The ones with recognizable signature are used automatically,
+ * while the rest can be configured via the $[Promise Adapter].
+ *
+ * This is a static option (can only be set prior to initialization).
+ *
+ * @param {boolean} [options.noLocking=false]
+ * Prevents protocol locking.
+ *
+ * By default, the library locks much of its protocol to read-only access, as a fool-proof mechanism.
+ * Specifically for the {@link event:extend extend} event this serves as a protection against overriding existing
+ * properties or trying to set them at the wrong time.
+ *
+ * If this provision gets in the way of using a mock-up framework for your tests, you can force
+ * the library to deactivate most of the locks by setting `noLocking` = `true` within the options.
+ *
+ * This option is dynamic (can be set before or after initialization). However, changing it after the library's
+ * initialization will not affect {@link Database} objects that have already been created.
+ *
+ * @param {boolean} [options.capSQL=false]
+ * Capitalizes any SQL generated by the library.
+ *
+ * By default, all internal SQL within the library is generated using the low case.
+ * If, however, you want all SQL to be capitalized instead, set `capSQL` = `true`.
+ *
+ * It is purely a cosmetic feature.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {string|Array<string>|null|undefined|function} [options.schema]
+ * Forces change of the default database schema(s) for every fresh connection, i.e.
+ * the library will execute `SET search_path TO schema_1, schema_2, ...` in the background
+ * whenever a fresh physical connection is allocated.
+ *
+ * Normally, one changes the default schema(s) by $[changing the database or the role], but sometimes you
+ * may want to switch the default schema(s) without persisting the change, and then use this option.
+ *
+ * It can be a string, an array of strings, or a callback function that takes `dc` (database context)
+ * as the only parameter (and as `this`), and returns schema(s) according to the database context. A callback function
+ * can also return nothing (`undefined` or `null`), if no schema change needed for the specified database context.
+ *
+ * The order of schema names matters, so if a table name exists in more than one schema, its default access resolves
+ * to the table from the first such schema on the list.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {boolean} [options.noWarnings=false]
+ * Disables all diagnostic warnings in the library (it is ill-advised).
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.connect]
+ * Global event {@link event:connect connect} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.disconnect]
+ * Global event {@link event:disconnect disconnect} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.query]
+ * Global event {@link event:query query} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.receive]
+ * Global event {@link event:receive receive} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.task]
+ * Global event {@link event:task task} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.transact]
+ * Global event {@link event:transact transact} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.error]
+ * Global event {@link event:error error} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).
+ *
+ * @param {function} [options.extend]
+ * Global event {@link event:extend extend} handler.
+ *
+ * This option is dynamic (can be set before or after initialization).

+/**
+ * @class QueryFile
+ * @description
+ *
+ * Represents an external SQL file. The type is available from the library's root: `pgp.QueryFile`.
+ *
+ * Reads a file with SQL and prepares it for execution, also parses and minifies it, if required.
+ * The SQL can be of any complexity, with both single and multi-line comments.
+ *
+ * The type can be used in place of the `query` parameter, with any query method directly, plus as `text` in {@link PreparedStatement}
+ * and {@link ParameterizedQuery}.
+ *
+ * It never throws any error, leaving it for query methods to reject with {@link errors.QueryFileError QueryFileError}.
+ *
+ * **IMPORTANT:** You should only create a single reusable object per file, in order to avoid repeated file reads,
+ * as the IO is a very expensive resource. If you do not follow it, you will be seeing the following warning:
+ * `Creating a duplicate QueryFile object for the same file`, which signals a bad-use pattern.
+ *
+ * @param {string} file
+ * Path to the SQL file with the query, either absolute or relative to the application's entry point file.
+ *
+ * If there is any problem reading the file, it will be reported when executing the query.
+ *
+ * @param {QueryFile.Options} [options]
+ * Set of configuration options, as documented by {@link QueryFile.Options}.
+ *
+ * @returns {QueryFile}
+ *
+ * @see
+ * {@link errors.QueryFileError QueryFileError},
+ * {@link QueryFile#toPostgres toPostgres}
+ *
+ * @example
+ * // File sql.js
+ *
+ * // Proper way to organize an sql provider:
+ * //
+ * // - have all sql files for Users in ./sql/users
+ * // - have all sql files for Products in ./sql/products

+ *
+ * const {QueryFile} = require('pg-promise');

+ *     return new QueryFile(fullPath, {minify: true});
+ * }
+ *
+ * module.exports = {

+ *     users: {

+ * - `false` - do not use $[pg-minify]
+ * - `true` - use $[pg-minify] to parse and minify SQL
+ * - `'after'` - use $[pg-minify] after applying static formatting parameters
+ *   (option `params`), as opposed to before it (default)
+ *
+ * If option `compress` is set, then the default for `minify` is `true`.
+ *
+ * Failure to parse SQL will result in $[SQLParsingError].
+ *
+ * @property {boolean} compress=false
+ * Sets option `compress` as supported by $[pg-minify], to uglify the SQL:
+ * - `false` - no compression to be applied, keep minimum spaces for easier read
+ * - `true` - remove all unnecessary spaces from SQL
+ *
+ * This option has no meaning, if `minify` is explicitly set to `false`. However, if `minify` is not

+ *
+ * Most of the time query formatting is fully dynamic, and applied just before executing the query.
+ * In some cases though you may need to pre-format SQL with static values. Examples of it can be a
+ * schema name, or a configurable table name.
+ *
+ * This option makes two-step SQL formatting easy: you can pre-format the SQL initially, and then
+ * apply the second-step dynamic formatting when executing the query.
+ *
+ * @property {boolean} noWarnings=false
+ * Suppresses all warnings produced by the class. It is not recommended for general use, only in specific tests
+ * that may require it.

+ * @description
+ * Extends {@link Database} for an automatic connection session, with methods for executing multiple database queries.
+ *
+ * The type isn't available directly, it can only be created via methods {@link Database#task Database.task}, {@link Database#tx Database.tx},
+ * or their derivations.
+ *
+ * When executing more than one request at a time, one should allocate and release the connection only once,
+ * while executing all the required queries within the same connection session. More importantly, a transaction
+ * can only work within a single connection.
+ *
+ * This is an interface for tasks/transactions to implement a connection session, during which you can
+ * execute multiple queries against the same connection that's released automatically when the task/transaction is finished.
+ *
+ * Each task/transaction manages the connection automatically. When executed on the root {@link Database} object, the connection
+ * is allocated from the pool, and once the method's callback has finished, the connection is released back to the pool.
+ * However, when invoked inside another task or transaction, the method reuses the parent connection.
+ *
+ * @see
+ * {@link Task#ctx ctx},
+ * {@link Task#batch batch},
+ * {@link Task#sequence sequence},
+ * {@link Task#page page}
+ *
+ * @example
+ * db.task(t => {
+ *       // t = task protocol context;
+ *       // t.ctx = Task Context;

+ * @description

+ * and transactions (methods {@link Database#tx Database.tx} and {@link Database#txIf Database.txIf}).
+ *
+ * Properties `context`, `connected`, `parent`, `level`, `dc`, `isTX`, `tag`, `start`, `useCount` and `serverVersion` are set just before the operation has started,
+ * while properties `finish`, `duration`, `success` and `result` are set immediately after the operation has finished.
+ *
+ * @property {*} context
+ * If the operation was invoked with a calling context - `task.call(context,...)` or `tx.call(context,...)`,
+ * this property is set with the context that was passed in. Otherwise, the property doesn't exist.
+ *
+ * @property {*} dc
+ * _Database Context_ that was passed into the {@link Database} object during construction.
+ *
+ * @property {boolean} isTX
+ * Indicates whether this operation is a transaction (as opposed to a regular task).
+ *
+ * @property {number} duration
+ * Number of milliseconds consumed by the operation.
+ *
+ * Set after the operation has finished, it is simply a shortcut for `finish - start`.
+ *
+ * @property {number} level
+ * Task nesting level, starting from 0, counting both regular tasks and transactions.
+ *
+ * @property {number} txLevel
+ * Transaction nesting level, starting from 0. Transactions on level 0 use `BEGIN/COMMIT/ROLLBACK`,
+ * while transactions on nested levels use the corresponding `SAVEPOINT` commands.
+ *
+ * This property exists only within the context of a transaction (`isTX = true`).
+ *
+ * @property {boolean} inTransaction
+ * Available in both tasks and transactions, it simplifies checking when there is a transaction
+ * going on either on this level or above.
+ *
+ * For example, when you want to check for a containing transaction while inside a task, and
+ * only start a transaction when there is none yet.
+ *
+ * @property {TaskContext} parent
+ * Parent task/transaction context, or `null` when it is top-level.
+ *
+ * @property {boolean} connected
+ * Indicates when the task/transaction acquired the connection on its own (`connected = true`), and will release it once
+ * the operation has finished. When the value is `false`, the operation is reusing an existing connection.
+ *
+ * @property {*} tag
+ * Tag value as it was passed into the task. See methods {@link Database#task task} and {@link Database#tx tx}.
+ *
+ * @property {Date} start
+ * Date/Time of when this operation started the execution.
+ *
+ * @property {number} useCount
+ * Number of times the connection has been previously used, starting with 0 for a freshly
+ * allocated physical connection.
+ *
+ * @property {string} serverVersion
+ * Version of the PostgreSQL server to which we are connected.
+ * Not available with $[Native Bindings].
+ *
+ * @property {Date} finish
+ * Once the operation has finished, this property is set to the Data/Time of when it happened.
+ *
+ * @property {boolean} success
+ * Once the operation has finished, this property indicates whether it was successful.
+ *
+ * @property {*} result
+ * Once the operation has finished, this property contains the result, depending on property `success`:
+ * - data resolved by the operation, if `success = true`
+ * - error / rejection reason, if `success = false`

+## TypeScript for pg-promise
+
+Complete TypeScript declarations for [pg-promise].
+
+### Inclusion
+
+Typescript should be able to pick up the definitions without any manual configuration.
+
+### Simple Usage
+
+```ts
+import pgPromise from 'pg-promise';
+
+const pgp = pgPromise({/* Initialization Options */});
+
+const db = pgp('postgres://username:password@host:port/database');
+
+const {value} = await db.one('SELECT 123 as value');
+```
+
+#### With Extensions
+
+The library supports dynamic protocol extensions, via event [extend], which requires
+explicit extension interface to be declared and parameterized, as shown below.
+
+```ts
+import * as pgPromise from 'pg-promise';
+
+// your protocol extensions:
+interface IExtensions {
+    findUser(userId: number): Promise<any>;
+}
+
+// pg-promise initialization options:
+const options: pgPromise.IInitOptions<IExtensions> = {
+    extend(obj) {
+        obj.findUser = userId => {
+            return obj.one('SELECT * FROM Users WHERE id = $1', [userId]);
+        }
+    }
+};
+
+// initializing the library:
+const pgp = pgPromise(options);
+
+// database object:
+const db = pgp('postgres://username:password@host:port/database');
+
+// protocol is extended on each level:
+const user = await db.findUser(123);
+
+// ...including inside tasks and transactions:
+await db.task(async t => {
+    const user = await t.findUser(123);
+    // ...etc
+});
+```
