Hi All, I have a few partitioned tables in my PostgreSQL database but I do not know yet how to make the ORM relationship() with partition constraint-exclusion<http://www.postgresql.org/docs/9.3/static/ddl-partitioning.html#DDL-PARTITIONING-CONSTRAINT-EXCLUSION> on the instance level. Constraint-exclusion does not work with joins and requires scalar values - the problem is that I would need to add an additional WHERE clause to the primaryjoin (which adds the partition key) if the relationship is accessed from the* instance level*, e.g. user.addresses. Is there a mechanism in relationship() to distinguish between class-based joins (User.addresses) and instance-level access?
