Django.db.utils.ProgrammingError: для столбца "id" таблицы "products_customer" указано несколько значений по умолчанию

После выполнения миграции я попытался выполнить миграцию, но получаю ошибку django.db.utils.ProgrammingError: multiple default values specified for column "id" of table "products_customer"

Но я удаляю эту таблицу клиентов из models.py как мне решить эту проблему?
