Oh dear. Those functions were actually just moved from pgstattuple, and
has been there since 8.2. Better backpatch that to the pgstattuple
functions in 8.2. It didn't occur to me to check the permissions on the
existing functions while I added the new ones.
I doubt there's any tools out there using those functions, so
restricting them to superuser only is probably ok.
