This feature is getting overdesigned, I think. It's already the case
that we log an error complaining that thus-and-such a page is corrupt.
Once PG has decided that it won't have anything to do with the page at
all --- it can't load it into shared buffers, so it won't write it
either. So the user can go inspect the page at leisure with whatever
tools seem handy. I don't see a need for more verbose logging.
