关于django：/ relation“main_post”中的ProgrammingError不存在

ProgrammingError at / relation “main_post” does not exist

您好我正在使用django和postgresql。我收到了上述错误。我有这样的数据库设置：

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

对于像sqlite这样的问题，我只能删除db(mydatabase)，但这次我看不到我的数据库在哪里。
