PostgreSQL数据库访问错误

编辑跳过第一部分,我发现(嗯,他们告诉我)问题出在数据库\Edit中

1) 复制项目

2) 删除了原始项目,但保留了副本

4) 复制了新的密钥

6) 用新的密钥更改了密钥

但这不起作用,它给出了和以前一样的错误:

The above exception was the direct cause of the following exception:

我不知道第一次是什么时候发生的,但我有另一个问题,可能是链接:我无法访问数据库。也许这是第一个问题的原因,而不是密钥。

我使用PostgreSQL,并使用实用程序标准pgAdmin III访问它。它为我提供了服务器的初始屏幕:PostgreSQL 9.5,我右键单击它并选择connect,它询问我密码,我给出但它抛出一个错误:

An error has occurred. Error connecting to the server: FATALE: autenticazione con password fallita per l'utente 'postgres'.

我只创建了一个数据库和用户,所以我有标准的postgres和我的数据库“possedimenti\u db”,用户名为“gm”。

我能做什么?我不介意现在的数据,我可以删除所有,但如果它不能让我访问,我不知道如何删除。

谢谢你

我的 settings.py :

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'possedimenti_db',
        'USER': 'gm',
        'PASSWORD': database_key,
        'HOST': host_key,
        'PORT': '5432',
    }
}

database_key 和 host_key 从外部文件导入。

编辑 你可以在答案的注释中看到解决方案,但问题是我的用户没有定义密码。
