Comment (by Simon Charette):
The latest version of the patch now supports filtering against annotations
masked by the usage of `values` and friends.
`queryset.filter(dept_max_salary__gte=2000).values("id")` now results in
{{{#!python
SELECT "col1" FROM (
SELECT * FROM (
SELECT "id" AS "col1", MAX OVER (...) AS "depth_max_salary" FROM
...
) "qualify" WHERE "dept_max_salary" >= 2000
) "qualify_mask"
}}}
