I read that PostgreSQL isn't supported by ISPConfig 3 but I would like to know if is it possible (and hopefully not terribly complex) to install PostgreSQL on Debian 6, allowing a client configured in ISPConfig 3 to access to a PostgreSQL DB. Thanks.
For install PostgresSQL you only need to do it with apt-get. And you can manage databases and user with phpPgAdmin (it's like phpMyAdmin) http://phppgadmin.sourceforge.net
Thanks for the reply. The installation of PostgreSQL and phpPgAdmin does not interfere with ISPConfig 3?
No. But you can't manage PostgreSQL's users/databases/limits with ISPConfig. And you can create an Alias like domain.com/phpmyadmin for PGSQL like domain.com/phppgadmin
