This great article showed how to use arp-scan to see if two pieces of hardware were claiming the same IP address.

In my case the server machine had a static ip address of Sure enough there was a conflict, as shown above. Then I ran arp-scan without the grep, found that.

Use arping on the IP address that is having connection issues. I had the same problem, even though I had a static IP address.

This issue comes from installing the postgres package without a version number. Although postgres will be installed and it will be the correct version, the script to setup the cluster will not run correctly; it's a packaging issue.

This runs locally using local permissions. The only drawback is that it is more typing than simply "psql". The other suggestion that someone made was to create a symbolic link between the two locations.

This also worked, but, the link disappeared upon reboot. I placed the symbolic link create command in the "start" section. Of course, when I issue a stop and start or restart command, it will try to recreate an existing symbolic link, but other than warning message, there is probably no harm in that.

I had a x-window open just for that operation. You can establish that superuser mode with sudo -i. I was changing the ownership on many folders while trying to find a solution.
