Well, that is exactly the point that needs some proof, not just
an unfounded assertion.

IMO, the main value of checksums is that they allow the Postgres
project to deflect blame.  That's nice for us but I'm not sure
that it's a benefit for users.  I've seen little if any data to
suggest that checksums actually catch enough problems to justify
the extra CPU costs and the risk of false positives.
