/**
* Create a PostgreSQL client using ext-pgsql.

* The client connects immediately and is ready to execute queries.
* For object mapping, provide a RowMapper (use pgsql_mapper() for the default).

* @param null|ValueConverters $valueConverters Custom type converters (optional)
* @param null|Client\RowMapper $mapper Row mapper for object hydration (optional)
*

* $client = pgsql_client(pgsql_connection('host=localhost dbname=mydb'));
*
* // With object mapping
* $client = pgsql_client(
* pgsql_connection('host=localhost dbname=mydb'),
