No, that would be exactly the *wrong* place, because that directory can
be on a RAM disk.  We need to put this somewhere where it'll survive
a shutdown.

One could imagine creating a PGDATA subdirectory just for permanent (not
temp) stats files, but right at the moment that seems like overkill.
If we accumulate a few more similar files, I'd start to think it was
worth doing.
