Firstly some extra information from php.net:
{{{ [http://tr.php.net/pg_connect] resource pg_connect ( string connection_string [, int connect_type] ) ... If a
secondcall is made to pg_connect() with the same connection_string, no new connection will be established unless you
pass SQL_CONNECT_FORCE_NEW as connect_type, but instead, the connection resource of the already opened connection will
bereturned. You can have multiple connections to the same database if you use different connection strings.
}}}
Here's a simple db wrapper class for 2 different db connections:
class dbw
{ /* Connection parameter variables. */ var connParam1; var connParam2;
function dbw() { /* Assigning values to conn. params. */ $this->connParam1 = "..."; $this->connParam2
="..."; }
function connect($connParam) { /* Pay attention to SQL_CONNECT_FORCE_NEW parameter. */ return
pg_connect($connParam,SQL_CONNECT_FORCE_NEW); }
/* ... */
}
/* Creating DB Wrapper */
$dbw = new dbw();
/*
* If we're not happy with the current connParam1 value:
* $dbw->connParam1 = "...";
*/
$dbConn1 = $dbw->connect($dbw->connParam1);
$dbConn2 = $dbw->connect($dbw->connParam2);

Yep. Just replace pg_connect line in the code with pg_pconnect. But I
(as PHP team) don't recommend using persistent connections. Please
read "Persistent Database Connections" [1] before deciding to use.

P.S. Next time, please try to use pgsql-php listen for PHP related questions.
