PgSQL support?

```
Hello! Thanks for great panel. Better than poweradmin (and as i can see, 
poweradmin development is halted)
Well, my request is to add PgSQL support to panel. For example, my supermaster 
uses PgSQL database. As i can see you have some sort of DB abstraction lib, but 
currently it works only with MySQL?
