Problems with config.php and non default ports (postgresql - sugarcrm)

Hello, I've a problem, we're using sugarcrm, and we have a database postgresql, but not in the default port, so, when I try to connect after I put the port in the db_port parameter, but seems like he not recognized, because still pointing to the other instance of the database that have the 5432 port, and I can see in that log when sugar it's trying to connect, even when I change the port.
