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.
That's pretty much what I was thinking. But yeah, at the time it's probably overkill - the main use today would be for better isolation of non-core extensions, but I'm not sure there are enough of those that want to write files in the data directory to care about..
