Description
Each database backend's DatabaseWrapper class should have a creation property that returns a subclass of django.db.backends.creation.BaseCreation, which contains all the information about how to create tables with the particular backend. BaseCreation is like BaseDatabaseOperations in django/db/backends/__init__.py, except it deals only with logic related to creation.
This was implemented in http://code.djangoproject.com/attachment/ticket/5106/backend-refactoring-v2-correct-bitrot.patch , but that patch is no longer valid, as some of it has been checked in already.

>>> from django.db import connection # We want connection.creation to return a backend-specific subclass # of django.db.backends.creation.BaseCreation.

I just added 5461.patch, and tested it as best I could with sqlite3 and mysql, obviously it needs testing on the other backends as well.

If v1.0 is the point at which we're guaranteeing interface compatibility, getting an interface like this one in place would seem to be fairly important. The most recent patch has some pretty bad bitrot, but it should be resurrectable.
