I have a similar project called `schemainspect` - It creates a data structure representation of a postgres schema. I then use this data in my database diffing project `migra`, to autogenerate database migrations. You can also use schema diffing to test that your production and development databases match explicitly. Overall it's a much more flexible but rigorous approach than the old-fashioned rails/django migrations.
