/**
 * PostgreSQL dialect that uses the [pg](https://node-postgres.com/) library.
 *
 * The constructor takes an instance of {@link PostgresDialectConfig}.
 *
 * ```ts
 * import { Pool } from 'pg'
 *
 * new PostgresDialect({
 *   pool: new Pool({
 *     database: 'some_db',
 *     host: 'localhost',
 *   })
 * })
 * ```
 *
 * If you want the pool to only be created once it's first used, `pool`
 * can be a function:
 *
 * ```ts
 * import { Pool } from 'pg'
 *
 * new PostgresDialect({
 *   pool: async () => new Pool({
 *     database: 'some_db',
 *     host: 'localhost',
 *   })
 * })
 * ```
