前一天我遇到了这个问题，我无法启动或重新启动 postgresql，并且会输出以下内容：
sudo service postgresql start并sudo service postgresql restart输出：
* Starting PostgreSQL 14 database server * Error: /usr/lib/postgresql/14/bin/pg_ctl /usr/lib/postgresql/14/bin/pg_ctl start -D /var/lib/postgresql/14/main -l /var/log/postgresql/postgresql-14-main.log -s -o -c config_file="/etc/postgresql/14/main/postgresql.conf" exited with status 1:

我检查日志输出并显示以下内容：

我尝试过这个：sudo service postgresql status但它会显示主机已关闭。并且sudo service postgresql stop还会停止服务器。
ps -ef | grep postgres输出：
ann 211 60 0 20:27 pts/0 00:00:00 grep --color=auto postgres
我也已经从此文件更改了本地主机sudo nano /etc/postgresql/14/main/postgresql.conf：
从listen_addresses: localhost到：listen_addresses = '*'
我已经检查过它是否正在监听Port: 5432。我甚至尝试过重启电脑，但还是不行。我在更新 Windows 11 后开始收到这些错误。
前一天已经发生过这种情况，但是，经过几次尝试后，只需从 Powershell 退出 Ubuntu 终端，它就会启动 postgresql。昨天，当我尝试时，所有这些错误都出现了。现在，当我尝试使用启动 postgresql 时sudo service postgresql start，postgresql 数据库服务器在主端口 5432 上启动它没有任何问题。我正在使用它来开发 Ruby on Rails 应用程序。
