操作错误：FATAL： database "django" does not exist

我是一个db傻瓜，我正在为我的django项目设置PostgreSQL.为此，我还使用了psycopg2.不过，数据库很复杂.就我个人而言，我想知道是否有办法在一个地方获得我所有的数据库和用户设置/信息.所以我知道连接到什么以及如何连接(我仍在运行local，所以没有安全问题？).

然而，我似乎没有创建这个数据库的"权限"，即使我连接到标准的"管理员"——用户"postgres".用我在安装时输入的密码("pw123").

django-project(settings.py):

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'django',                      
        'USER': 'postgres',
        'PASSWORD': 'pw123',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

CMD -> python manage.py shell (after importing django.db connection)

>>> cursor = connection.cursor()

OperationalError: FATAL:  database "django" does not exist

我是不是在安装过程中做错了什么？我能改正吗？我应该考虑重新安装所有东西吗？我该怎么做呢？数据库把我搞糊涂了:p
