You mean, test if we're in a restricted process, and then refuse to run
unless that is so? That would be a simple way out of the problem, but
I'm not really sure that it "fixes" the issue because Win32 people
normally expects stuff to run by dropping privs internally.
Maybe that's something we should leave for later, though, and fix 9.2 by
doing what you propose (which is presumably going to be a much simpler
patch). Clearly having pg_ctl just crash is not a good situation.
