django-admin-interface: migrate fails at "change_related_modal_background_opacity_type"

Hi there. Thanks for the great interface. I’m trying to migrate from a function setup with Python 3.6, Django 2.1.5, and admin-interface 0.9.1 . When I run migrate on my development computer I end up with the following traceback. I’m happy to help debug but the process of debugging if I can.

` Applying admin_interface.0008_change_related_modal_background_opacity_type…Traceback (most recent call last): File “/home/ace/.local/share/virtualenvs/website-10j77PrM/lib/python3.6/site-packages/django/db/backends/utils.py”, line 85, in _execute return self.cursor.execute(sql, params) psycopg2.OperationalError: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

The above exception was the direct cause of the following exception:
