Description
pg_close(?PgSql\Connection $connection = null): bool
pg_close() closes the non-persistent connection to a PostgreSQL database associated with the given connection

Using pg_close() is not usually necessary, as non-persistent open connections are automatically closed at the end of the script.
If there is open PgSql\Lob instance on the connection, do not close the connection before closing all PgSql\Lob instances.

An PgSql\Connection instance. When
