   Thanks for your reply, Aragorn. After investigating a few systemctl   
   isolate and start commands, I started the tar process in single user mode.   
      
   A fairly disasterous outcome, I'm sorry to say. The tar process started   
   to throw "insufficient space"  and "can't perform mkdir" messages. I   
   can't find any reference to tar using temporary files, and in single   
   user mode, I couldn't see any obvious temp files.   
   I deleted a few MBs from /tmp and restarted; now I get to the graphical   
   login screen but my password isn't recognised (nor can I log in as   
   postgres, which has no password). So I'm about to boot from a Live Disk   
   to see what I can see.   
   Later: It appears that /newusr wasn't mounted, which accounts for the   
   lack of space - oops!
