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 script brake it
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
