32242	@override_settings does not work with DATABASES	Peter Inglesby	nobody	"#19031 introduced a warning that `@override_settings` ""may not work with DATABASES"".

In the last seven years, things have changed so that `@override_settings` does not work with DATABASES at all.

This is because once `django.setup()` has been called, `django.db.connections.databases` is cached via `cached_property`, and so overriding the settings has no effect.

As such, the warning should be changed to an exception.

(I fully accept that anybody messing around with `DATABASES` like this deserves all the trouble they encounter!)"	Cleanup/optimization	closed	Testing framework	3.1	Normal	wontfix			Unreviewed	0	0	0	0	0	0
