No, I'm using PostgreSQL v9.3.9. Sorry, I should have mentioned my setup. I tested this with

- SQLAlchemy 0.9.6 / psycopg2 2.5.3 / Python 2.7.5
- SQLAlchemy 1.0.8 / psycopg2 2.6.1 / Python 2.7.10

Is 1.0.9 available for download to test (or is this even applicable if I'm not using Oracle)?
that was a totally cx_Oracle thing that wouldn't apply elsewhere.

So, next thing, has anything changed other than database data? versions of anything?

Next thing, data-level. If the mapping you have here is to a SELECT or a join of some kind, if the columns that are the "primary key" come back as NULL, that won't return an ORM-level entity. Rows with a null primary key are omitted. echo='debug' would help to illustrate the row coming back.





Thanks,
Demitri
