[volodymyr-hordiienko]

Hi everyone! There is issue with async PGSQL PDO driver \Hyperf\Database\PgSQL\DBAL\PostgresDriver, its using for both \Hyperf\Database\PgSQL\PostgreSqlConnection and \Hyperf\Database\PgSQL\PostgreSqlSwooleExtConnection as Doctrine driver but allows only \Swoole\Coroutine\PostgreSQL connections. Should allow PDO version also
