Ah so. Thanks for following up.
It may be unthinkable hubris to say this, but ... I am starting to
notice that a larger and larger fraction of serious trouble reports
ultimately trace to hardware failures, not software bugs. Seems we've
done a good job getting data-corruption bugs out of Postgres.
Perhaps we should reconsider the notion of keeping CRC checksums on
data pages. Not sure what we could do to defend against bad RAM,
however.
