this was the minimal code demonstrating the issue.
i planned to do this many times for bulk insert into the table in
database-independent way.

seems there is some other prob too:
- in 0.3 it is issued 2 statements:
select nextval('"Manager_id_seq"')
and then:
INSERT INTO "Manager" (duties, name, id) VALUES (%(duties)s, %(name)s,
%(id)s)
with the ids got from the db and the other parameters.
- in 0.4 it is issued only the last insert with all ids None which
leads to the error

even in this case the error is the same in 0.4:
