We use sequences, which is neither of those, and has been very reliable for us.

I included the disclaimer that you need a schema that follows strict sequence name => table name conventions, but that's what we have.

Right -- we also have ~2-3 "stable" rows of users that every test needs, so we can skip re-creating for each test.
