Looking for a schema / database migration tool

[Yannick Gingras]

Greetings Alchemists,
I'm looking for a schema migration tool, ideally one that works well
with SQLAlchemy. I know about sqlalchemy-migrate but I find its
monotone numbering scheme hard to reconcile with distributed
development. More details on that specific problem on their mailing
list:

http://groups.google.com/group/migrate-users/browse_thread/thread/f95ac435aa27280c

Are there any other tool that could do the job? How hard would it be
to modify sqlalchemy-migrate to work with dependencies instead of
sequential version numbers?

Best regards,
