尝试安装postgreSQL，看起来很喜欢我搞砸了。我首先使用以下命令删除postgres。
[ec2-user@ip-10-183-130-45 /]$ rm -rf /var/lib/pgsql/data
[ec2-user@ip-10-183-130-45 /]$ sudo rm -rf /var/pgsql
然后尝试initdb，由于某种原因失败，
[ec2-user@ip-10-183-130-45 /]$ sudo service postgresql initdb
Initializing database: [FAILED]
但是当我检查时，initdb确实创建了pgsql文件夹，
[ec2-user@ip-10-183-130-45 var]$ ls -l
total 80

所以我尝试启动postgresql，这也失败了
[ec2-user@ip-10-183-130-45 var]$ sudo service postgresql start
/var/pgsql is missing. Use "service postgresql initdb" to initialize
the cluster first.
[FAILED]
有人可以提供帮助吗，身份证明我做错了什么？使用postgresql-9.2-1.19。

我认为存在误解。你说你删除了一些postgres文件，然后想知道为什么它不起作用？
我建议：
