Replying to [comment:2 Simon Charette]:
> I agree that either an exception should be raised and the
[https://docs.djangoproject.com/en/2.1/ref/models/querysets/#union
documentation be adjusted] to explicitly mention aggregation won't work or
adding an aggregate function should perform a subquery pushdown.
Please can help, how can rewrite query for correct work???? My boss shut
me in close time, but i stock there)
