I was reminded today that we still haven't done anything about this:

At this point there are no shipping Fedora versions that don't emit this
gripe, and F15 is even about to go EOL.
The previous discussion thread at
http://archives.postgresql.org/pgsql-hackers/2011-09/msg00794.php
went off into the weeds of what was in my opinion over-design.
I still think it's sufficient to do what I suggested initially:

and would like to squeeze that into 9.2 so that we're only a year late
and not two years late in responding to this issue :-(.
Objections?
