You have to use pg_connect to connect to postgresql . If you want to use PDO see this article , or php documentation . For pg_connect , I suggest you to do this:

$conn_string = "host=".$host." port=".$port." dbname=".$db_name." user=".$db_user." password=".$db_password;
$db_conn = pg_connect($conn_string);

If it's not connecting try to change $port to 5432 . 5432 is default port value of postgresql .
