I just switched from using PHP and Mysql to Python / Django and Postgresql. I am having trouble with the setup of Postgresql permissions. I am locked out of some parts of the system and am unsure when to use postgres login vs user login. Most of the Postgresql instructions are written for non-debian like installations. They have one do a bunch of things that Debian does automatically (I think). I found the Debian README confusing, especially in regards to setting up a special shell that I don't think I need. Most of the instructions seem to have already been done automatically.
