Comment (by anonymous):
Can you please explain how to do it through django without using the
patch?
Replying to [comment:2 akaariai]:
> The problem here is that PostgreSQL would need a type cast to int. So,
the SQL should look like SUM("some_boolean_field"::int) for the SUM to
work. However I am not sure if doing this in Django is a good idea, mainly
because this would complicate the code somewhat, and something like #11305
would solve the issue for the user by allowing generation of SQL like in
the Mozilla bug report.

as wontfix for the reasons mentioned above. Could this be marked duplicate
(or "related to") to #11305?
