отношение «django_session» не существует при переходе от sqlite к postgres

/ 09 июля 2020

Понятия не имею, что я здесь делаю не так. Я пытаюсь перенести свою базу данных на postgres, но я сталкиваюсь с этой ошибкой: 

    relation "django_session" does not exist
LINE 1: ...ession_data", "django_session"."expire_date" FROM "django_se..

Я удалил свою старую базу данных, перешел, попытался выполнить поддельную миграцию, я вижу, что созданы новые таблицы в pgadmin, поэтому я не уверен, почему я получаю эту ошибку. Я также убедился, что мои настройки pgadmin синхронизированы c с моими django настройками. Кроме того, я могу видеть свои таблицы db на pgadmin, но я не вижу django сессий или мой db на pgadmin.

Я получаю предупреждение, когда выполняю команду manage.py run server 

    You have 3 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): dating_app, sessions.
Run 'python manage.py migrate' to apply them.

И затем, когда я запускаю manage.py migrate, это трассировка, которую я получаю

Traceback (последний вызов последний):
