Suddenly my integration between flask-openid / flask-login or just flask in general wasn't working at all.
After a couple of debugging hours, I found the following link: https://github.com/celery/celery/issues/634
Basically they added as a default in postgres.conf
ssl = true
Since I don't have ssl I didn't knew what hit my box
I can't find nothing directly related in the changelog: http://changelogs.ubuntu.com/changelogs/pool/main/p/postgresql-9.1/postgresql-9.1_9.1.8-0ubuntu12.10/changelog that mentions why that setting is forced to true, but either way, if you are using Postgres, and celery or flask, you will notice that the application will start to crash and it will start throwing , using sqlalchemy, operational errors exceptions.
