Support postgresql schemas

[andrecavallari]

You could improve the support for Postgresql schemas, in one of my applications I have some additional schemas, but cant change schemas in your plugin...

And wow, very nice plugin for Rails!

@andrecavallari thanks, it might be interesting, but unfortunately we need a volunteer to do this. I'm a bit busy. Maybe you can code it by yourself and just create PR
