/relation "main_post"にProgramErrorが存在しません

Question

こんにちは私はdjangoとpostgresqlを使用しています。上記のエラーが発生しています。私は、データベースは次のように設定している：sqliteのと、このような問題のため

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.postgresql_psycopg2', 
     'NAME': 'django_db', 
     'USER': 'xxx', 
     'PASSWORD':'xxxx', 
     'HOST':'localhost', 
     'PORT':'5432', 
    } 
} 

、私はちょうどデシベル（MyDatabaseという）を削除していたかもしれないが、私のDBがある場合、この時間は、私が見ることができません。 sqlflushから
