I have stayed quiet about this since I wanted to hear what others
thought of the above suggest fix.  I took the detach code straight from
the postmaster daemonize function.  Perhaps I didn't do something right
but that was the example I followed.  Thoughts?  Anyone else had this
problem?

BTW, I think this will be moon in 7.5 since it looks like pg_autovaccum
will be launched by the postmaster.
