我使用的是arch linux (4.8.13-1-ARCH)。我正在尝试按照here的指示设置PostgreSQL。
在执行完
[postgres@BitBox ~]$ initdb --locale $LANG -E UTF8 -D '/var/lib/postgres/data'
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
pg_ctl -D /var/lib/postgres/data -l logfile start
成功地,我使用exit命令返回到我的常规用户。
[postgres@BitBox ~]$ exit
logout
然后,在尝试启动postgresql.service时,我得到了以下错误:
[code_master5@BitBox ~]$ sudo systemctl start postgresql.service
Failed to start postgresql.service: Unit postgresql.service not found.
我甚至没有得到服务的状态:
[code_master5@BitBox ~]$ sudo systemctl status postgresql.service
Unit postgresql.service could not be found.
我卡住了!

最后,我解决了这个问题。已存在一个文件
/usr/lib/systemd/system/postgresql-9.6.service
所以,可能是由于这个文件的存在,我无法启动postgresql.service。然后我尝试启动postgresql-9.6.service,如下所示:
[code_master5@BitBox ~]$ sudo systemctl start postgresql-9.6.service
Failed to start postgresql-9.6.service: Unit postgresql-9.6.service not found.
而且,正如您看到的输出,它再次失败。
我只是使用sudo删除了这个文件,因为我认为可能是由于这个文件的存在,相关程序没有创建postgresql.service文件。然后我重新启动了系统。从那时起,它工作得很好,您可以看到下面的输出:
[code_master5@BitBox ~]$ sudo systemctl status postgresql.service
[sudo] password for code_master5:

我当然想警告所有有同样问题的人。请照我说的做,风险自负。因为这些是系统文件。摆弄这些东西会毁了你的周末!
不过,在这一点上我还是有点困惑。欢迎解释!

试试这个:
service postgresql-10.service restart
service postgresql-XX.service restart

我发现这两个命令非常方便。虽然这篇文章很老了,但也许其他人将来会从中受益。
systemctl list-units|grep postgresql
service postgresql-12.service restart
