"psql -U postgres -h localhost" 没问题！！
【问题讨论】：
【参考方案1】：-
以任何用户身份连接。以超级用户 postgres 连接（注意，超级用户名在您的安装中可能不同。例如，在某些系统中，它称为 pgsql。）
psql -U postgres
或
psql -h 127.0.0.1 -U postgres
（请注意，使用第一个命令您不会总是与本地主机连接）
-
重设密码
ALTER USER my_user_name with password 'my_secure_password';
-
恢复旧的 pg_hba.conf，因为保留它非常危险
cp pg_hba.conf-backup pg_hba.conf
-
重新启动服务器，以便使用安全的 pg_hba.conf 运行
sudo /etc/init.d/postgresql restart
【讨论】：
对不起，现在..当我“createuser ...'jet'”时。系统询问密码...我无法使用 postgres.ànd 文件的密码连接 /root/pgpass:"127.0.0.1:5432:*:postgres:123456"【参考方案2】：你有错误的数据库设置
DATABASES =
'default':
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'comadicui',
'User':'postgres',
'PASSWORD':'123456',
'Host' : '127.0.0.1',
'Post' : '5432',
试试看
DATABASES =
'default':
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'comadicui',
'USER':'postgres',
'PASSWORD':'123456',
'HOST' : '127.0.0.1',
'PORT' : '5432',
当您在数据库配置中没有 USER 时，django 将 root 用户作为默认用户
【讨论】：
【参考方案3】：我知道这是一个老问题，但这对我有用
pip install python-dotenv
然后在manage.py中添加
from dotenv import load_dotenv
load_dotenv()
在 .env 文件中
export DB_NAME=databasename
export DB_USER=db_use
export DB_USER_PASSWORD=password
export DB_HOST=host
现在重新启动服务器以运行。
