Comment (by Curtis Maloney):
Replying to [comment:3 Tim Graham]:
> Thanks for clarifying. Maybe the Oracle-specific
[https://docs.djangoproject.com/en/dev/ref/settings/#create-db CREATE_DB]
setting in DATABASES 'OPTIONS' does what you want to do for PostgreSQL?
Possibly that might just be another way to do "keepdb" -- I didn't
investigate enough to confirm.

From the docs:
{{{
If it is set to False, the test tablespaces won’t be automatically created
at the beginning of the tests or dropped at the end.
}}}
This is _close_ to what I was after. However, I'd want it to create and
tear down the models, etc.
So really we want to build a matrix of steps:
1. (a) Create DB --OR-- (b) Clear DB
1. Apply migrations
1. Revert migrations
1. Drop DB
Normally we affect all steps, with 3 implied by 4. Using --keepdb skips 3
and 4. I'm looking for a way to allow only 1(b), 2, and 3.
My current solution to step 3 is excessive, in that it will drop
_everything_, not just the objects we created in migrations. I don't
believe there is currently a simple way to migrate everything to ZERO,
instead we'd likely need to iterate the installed apps and do them
individually.
