BTW, am I right in guessing that you got into this fix by sloppy
application of the directions for fixing template0 for the recent
security issues?

Although I dislike last-minute fixes, I am strongly tempted to put in
the ignore-datallowconn-if-standalone change in all the releases we are
about to make. It'd be a one-liner that is very unlikely to break
anything, and I have this nasty feeling that you may not be the only
guys to make this mistake.
