Thanks for the quick reply.
If I modify the name of the sequence in the test, it reproduces what I have
experienced.
When I check the details on the sequence in postgres, there is no table owner
or column specified by the sequence 'test_user_id_seq'.. and I would expect to
see both tables `a` and `b`.
class IdMixin(object):
id = Column(Integer, Sequence('test_user_id_seq', start=10000),
primary_key=True)
I will write a complete self contained test, that anyone can run. But wanted to
give my immediate feedback.
Thanks so much,
Mat
