Comment:
I think the correct solution here will be to make
`Subquery.get_group_by_cols` return all its `OuterRef` expressions when
`alias is None`; that is the ones contained in its annotations and where
clause.
That would result in an additional `GROUP BY T4."position"` in the outer
query as PostgreSQL expects.
