PostgreSQL 9.6 CentOS 7 LibreTime-postgresql.service的作業失敗

Question

我正在嘗試將其與LibreTime一起使用，但是由於某種原因，它無法啟動postgresql。

 systemctl start postgresql Job for postgresql.service failed because the control process exited with error code. See "systemctl status postgresql.service" and "journalctl -xe" for details. 

這是journalctl -xe的信息-注意-我出於隱私目的更改了我的實際主機名：

journalctl -xe

我是CentOS的新手，正在嘗試按照本教程進行操作。 這似乎是唯一的失敗點。 http://libretime.org/manual/preparing-the-server/

在此先感謝您的協助！

-edit-這是完整的代碼，哎呀：

Answer 1

好的，所以這是一個糟糕的“答案”，但是我通過拉下9.6版並安裝了9.3版來“修復”它。

再次感謝。
