31021	0011_update_proxy_permissions crashes in multi database environment.	haudoing	Mariusz Felisiak	"The tutorial said that we can omit to set the default database if default doesn't makes sense
https://docs.djangoproject.com/en/2.2/topics/db/multi-db/#defining-your-databases


But the following migration script doesn't work after configuration with empty default database
https://github.com/django/django/blob/stable/2.2.x/django/contrib/auth/migrations/0011_update_proxy_permissions.py

on line 42, it use

{{{
            with transaction.atomic():
                Permission.objects.filter(
                    permissions_query,
                    content_type=old_content_type,
                ).update(content_type=new_content_type)
}}}
This will brake the migration if default database doesn't set
