Comment (by razielvamp666):
Replying to [comment:1 Mariusz Felisiak]:
> Thanks for this report. However a lot of things happen outside of
Django, you have many 3rd-party packages, a custom `Operation` in
migrations, etc. The main issue is that you're using the `query` attribute
to generate an SQL which is not recommended, documented, or supported.
Moreover, this helper has issues with parameters (see #25705) and doesn't
work when the `default` database is empty (see #25947). I'm not marking
this as a duplicate of #25947 as fixing it will not make `.query` the
recommended way to generate an SQL. I would use a raw SQL in your case.

Thank you for answer.
Sorry, I didn't notice that was used little bit our code too. Not just
standard libraries.
But, Is I will wrong if I say:
1. Django support multiple databases
2. `django/db/models/sql/query.py` not support multiple databases because
it uses `DEFAULT_DB_ALIAS` and no matter how and when it run. Result will
be always same for non `default` DB
3. `django/db/models/sql/query.py` is a standard part of Django
4. standard part of Django not support multiple databases
5. => Django not support multiple databases (at least for all features)
Isn't this a kind of bug?
