For SQL in general SQLZoo is a horrible looking website, but if you go through the tracks you will actually learn a bit. If you're having issues with using postgresql with Rails and heroku (judging from post below), then you're really asking how use those three things together. In this case there are plenty of examples of all the things that can go wrong and how to fix them on stack overflow. If you'd like to send me the errors you're getting and other details of why it's breaking I'd be glad to field a couple emails (contact in profile).
