PostgreSQL does not guarantee row order without ORDER BY, unlike SQLite which implicitly returned rows by rowid. This caused bugs like get_team_by_owner returning the wrong team. Solution: Override select() in BaseModel to add default .order_by(cls.id). Explicit .order_by() calls will override this default. Tested with joins, where, limit, aggregations - all work correctly.
