Indeed, and why would that not apply to Windows as well?  AFAIK, inclusion
of --single in this list is just plain nuts.  The most likely result of
running that way is creation of root-owned files inside $PGDATA, which
would cause havoc for later normally-privileged postmasters.

I will go and commit this, without the #ifdefs and without the --single
exclusion.
