This is a simple example of this function, which returns the name of which PostreSQL Database you are currently connected to. <?php $pgsql_conn = pg_connect("dbname=mark host=localhost"); if ($pgsql_conn) { print "Successfully connected to: " . pg_host($pgsql_conn) . "<br/>\n"; } else { print pg_last_error($pgsql_conn); exit; } ?> This function is extremely useful for sites which connect to multiple Postgresql services. Regards, --mark
