changed by other users: there is a SessionExtension that collects info about

Just one thing: I know the syntax _class__attribute to access hidden python

Not really... in postgres, you can ask to consume the next sequence
value with SELECT NEXTVAL('sequence_name') and explicitly set that as
primary

hey mike,
Just to confirm - trunk fixes problem with deletion.
Additionally, I have removed the lazy loading condition and it
maintains the speed of the query.

This works here on MSSQL/pymssql with a small change:
-- j = Job(TEST1, datetime.datetime.now())
++ j = Job(1, datetime.datetime.now())
MSSQL (and most other db engines) are going to enforce type on the
