To change the port on the Postgres server, login to the PostgreSQL appliance > Configure PostgreSQL > change port to 5433 (or something other than 5432) > Submit.
Now from the main 9443 PostgreSQL Appliance Tools page select phpPgAdmin > click on PostgreSQL in the left column > attempt to login with valid credentials. The authentication will fail because phpPgAdmin config is not updated with the changed port.
To resolve, update the port in this file: /opt/novell/srv/www/htdocs/phpPgAdmin/conf/config.inc.php // Database port on server (5432 is the PostgreSQL default) $conf['servers']['port'] = 5432;
This problem has been reported to development. If you need to change the port please use this workaround to manually update the config file.
