That sounds about right, except that I don't want to to require both
sa-migrate and alembic in nine.  So I think that Alembic would see
"empty DB" and "0.8.9" as its first two schema versions.  If you have
a different base schema version, you'll need to use 0.8.9 to upgrade
to that version, *then* install a version of nine and upgrade from
there.

Now that sqlalchemy-migrate is being maintained, though, we can at
least allow users to run a newer version of sqlalchemy!
