This is just a rebased version of the patch by Simon here:

+u5nmkw_gbs6qq_y8-rjgl1v7mvw2hwbhartb8lojhnpfx...@mail.gmail.com
There are other things I'd like to do, like:
* include page# in checksum, and perhaps relfilenode or object OID (but
those two might cause difficulties)
* use TLI field instead of page version, if that is the consensus
(though it seems some may still disagree with that)
* we might want to make it slightly easier for external utilities, like
for backup/replication, to verify the pages
* optionally protect temporary files and local buffers
* come up with a robust way to determine that all pages in the database
are protected
* protect uninitialized pages
But not all of these will make the first patch. This is just a starting
point to reignite the discussion.
I welcome any feedback.
Regards,
Jeff Davis
