Running Sqlalchemy 0.5.8 (can't upgrade right now) with Postgres
8.1.X.
A table contains an array column:
users text[]
In SQL I would query
select ...where 'jim' = ANY(users)
How would I query this using the ORM layer?

Generically the pattern is called: insert_or_update
SQLAlchemy calls it: merge
Rails calls it: find_or_create
Symfony implements it as: setNew(false) and then save()
MySql calls it: insert on duplicate update
