Thanks for the the advice Domen, that seems to clear up many of my problems :-)
So right now I'm able to create a session, pull a few thousand records
and then close that session. Then those instances get displayed in
the gui and might get changed by some other threads, which will commit
them
Mike, thanks so much for responding.

It is OK now.
To make it easy for the developers not to care about the history tables and
versioning, is it possible not to define _history models manually and make
history_meta to generate them automatically?

The problem is i defined the history class with the following way (examining
the test_versioning file):
--
Base = declarative_base(metaclass=VersionedMeta)
class User(Base):
__tablename__ = 'users'
id = sa.Column(sa.Integer, primary_key=True)
Hello everyone,
I switched from sqlite to postgres and the problem is that many tables
are not filled with data when my util adds them (while there was no such
problem with sqlite):

Hi Mike, I tried out the merging, but am hitting the snag that objects

uh wait, how are you adding your objects to the Session ? are you
calling commit()? I notice there's no commit in the logs which is
likely the source of your issue.
I do call commit, it just turns out I missed an exception in the log
that took place before

can you produce a small test case illustrating this ?
Sure, I'll do my best to produce one for you.
we have tests
exercising merge() in conjunction with delete-orphan cascade but
perhaps there is a bug here.
