Должен быть владельцем отношения django_site, когда manage.py migrate

После долгих поисков о postgre, о manage.py killorphant, о django_site, ничто не могло помочь мне с этой ошибкой:

Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  Applying sites.0002_auto_20150929_1444...Traceback (most recent call last):

    return self.cursor.execute(sql, params)
psycopg2.ProgrammingError: must be owner of relation django_site**

Вышеупомянутое исключение было прямой причиной следующего исключения:

Итак, после проверки и повторной проверки, django-сайт находится в списке установленных приложений, site_id = 1; моя база данных работает, за исключением некоторых проблем с изображениями. Ну, тогда я попытался выполнить некоторые миграции, но эта ошибка продолжает работать, и теперь я отчаянно пытаюсь найти проблему.

Кто-нибудь знает об этом?
