behavior, though it would be nice to get a bit of clarity.
Just to refresh, I've got an implementation very similar to the
adjacency list example. Michael has helped me to eager load a subset
of a node's children with a call to
Hi,
I did some more investigation about this subject and found the source
for this problem and perhaps some hints for people willing to help out
with this problem:
Around line 1002 of mapper.py there is a call to

Why this fails? It seems because two

I have begun using SQLAlchemy in earnest for a database project I've

I tested my hypothesis, and inactivated the trigger on the Project
table, then added a Sequence('project_id_seq') to the project_id
column in the project table definition, and the updates work like a
charm.
So, is it not permissible to have triggers set on tables if one is

giving back OIDs, which according to PG docs are off by default and
are deprecated:

Let's say the second table is called 'addresses' and has a two-column
