You might take a look at my writeup on dynamic models,[1] which specifically covers a way to specify Django models in a database, which can be changed at run-time. However, I haven't looked at what it would take to actually commit changes to the already-synced tables. I have a feeling Django Evolution[2] will help with this, but I haven't done any testing with it yet.
