BTW, another idea for "connecting" to PostgreSQL as different users would be to actually have Django connect to PostgreSQL as a superuser and then (probably in some early middleware) execute SET SESSION AUTHORIZATION to switch permissions. This is probably easier and more robust and it's easier to reuse connections.
