fwiw, i have run installcheck (serial and parallel) and isolationtest,
also combination of those (one installcheck, one isolationtest) at the
same time while executing vacuum full, reindex database and manual
checkpoint...
i also check that the bgwriter was doing some work.
i did all of this in a master node in a cluster with a standby and a
cascade standby that were later promoted... and i have no problem with
checksums at all, so i would say that the combination of Jeff's and
Andres' patches fixed the problems we have seen until now
