Here's an updated patch against head.
NOTE, it appears that this (and the previous) patch PANIC with
"concurrent transaction log activity while database system is shutting
down" on shutdown if checksumming is enabled. This appears to be due
to FlushBuffer (lines 1821-1828) during the checkpoint-at-shutdown.
Other than that, I haven't looked into what needs to be done to fix
it.
Similarly, I ran a pgbench, performed a manual checkpoint, and
corrupted the tellers table myself using hexedit but the system didn't
pick up the corruption at all :(
Alvaro, have you given up on the patch or are you just busy on
something else at the moment?
