I've chmod 666 /dev/null and now postgres installs OK. However I
hesitate to go further as this server is on a VPS. Could that be why the
perms were not set properly? I have been running this server for about 3
weeks just with a basic mail setup - Postfix/Courier/Procmail passing
all mail through Spamassassin on another server, so some of the obvious
spam I have been sending to /dev/null which seems to work. I am
unfamiliar with the deployment of VPS's, I just use them, so I assume
this should have been setup when the VPS was created.
