I don't know what PHPMyAdmin is, but there is a Perl administration utility that allows you to write plugins. It's called Webmin

Of course, since you're a perl coder you would be wanting to write your own, based on something like NetServer

UPDATE: Who voted this down? I was offering factual information that was correct. Webmin comes with modules that allow you to manipulate Postgresql and MySQL databases, tables, users and other objects through a web interface. Did you even bother to follow the link and check it out?
