I was testing an app I made in Django using sqlite. Virtualenv was complaining about an error. I don't remember what it was but it was completely irrelevant to the DB. Something like couldn't access the virtualenv's python bin or something. After spending days on it, I was like screw it, I'll come back to that error later and started moving the app towards production state. When I switched to postgresql the error resolved itself.
