Ubuntu 22.04重启后PostgreSQL 14无法启动，提示套接字文件不存在的问题求助

各位大佬好，我遇到个棘手的问题：之前在Ubuntu 22.04上装了PostgreSQL 14.9，一切运行都正常，结果重启系统之后，连接数据库时直接报错了，错误信息如下：

connection to server on socket "/var/run/postgresql//.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket?

我自己试着做了一些排查，执行了几个命令，结果如下：

执行service postgresql status的输出：

● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)
Active: active (exited) since Fri 2023-09-08 08:40:41 MSK; 1h 0min ago
Main PID: 3142 (code=exited, status=0/SUCCESS)
CPU: 3ms

systemd[1]: Starting PostgreSQL RDBMS...
systemd[1]: Finished PostgreSQL RDBMS.

执行pg_lsclusters的输出：

Ver Cluster Port Status Owner    Data directory              Log file
14  main    5432 down   postgres /var/lib/postgresql/14/main /var/log/postgresql/postgresql-14-main.log

之后我尝试启动特定的集群服务：

$sudo systemctl start postgresql@14-main

结果又报错：

Job for postgresql@14-main.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status postgresql@14-main.service" and "journalctl -xeu postgresql@14-main.service" for details.

现在实在不知道该怎么继续排查了，有没有大佬能指点一下？
