Subject: Server deleted then restored - now postgresql will not start
Date: Fri, 22 Apr 2016 10:10:51 +0100

123-REG have had a problem where some virtual servers were accidentally
deleted. My server has finally been restores, but now my Postgresql service
will not start.
systemctl start postgresql
returns a failed state. Both of the following commands gave nothing useful.
systemctl status postgresql
journalctl -xn
The only helpful information I have found is the log file below.
Firstly, I do not want to make the situation worse, but I need to get the
service fixed.
Can anyone suggest the steps I need to take, or a suitable web page to read.
Gary
