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.
