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.
