Hi, I am trying to update my project to Django 2.2 (we are currently on 2.0.13). When I launch `python manage.py migrate`, I get this error message when migration auth.0011_update_proxy_permissions is applying (full stacktrace is available here <https://dpaste.de/5nJJ>): django.db.utils.IntegrityError: duplicate key value violates unique constraint "idx_18141_auth_permission_content_type_id_01ab375a_uniq" DETAIL: Key (content_type_id, codename)=(12, add_agency) already exists.
It looks like the migration is trying to re-create already existing entries in the auth_permission table. At first I though it cloud because we recently renamed a model. But after digging and deleting the entries associated with the renamed model from our database in the auth_permission table, the problem still occurs with other proxy models. I search for a ticket about this on the bug tracker but found nothing. Can someone help me on this? I guess I can keep deleting problematic entries from our database one by one but it will take a long time and it doesn't look right.
