Let's say I'm using a uuid PK for my models with a ` server_default` set to
`gen_random_uuid()` (in PostgreSQL). Is there a way to ensure the
server_default value? I would like to catch any INSERT or UPDATE
statements that set the PK value and raise an error if possible.

When I merge() an object without a PK, I expect similar behavior to add(),
in that the autogenerated PK is returned and set on the object. Is that
not expected behavior?

Hi, I'm wondering what the correct syntax is for a nested correlated
exists subquery?
I have Message and Engagement declarative tables and here is the query i'm
trying to replicate:
select *
from message m
where exists (
select 1 from engagement e
where m.engagement_id = e.id
and exists
