If you somehow have 3+ bit errors coming out of ram on an ECC board, you have much bigger problems than trying to verify your postgres data via checksum.

AFAIK RowHammer attacks can cause multiple bits to flip in a row[1], no?

But sure, it's not for the vast majority of folks.

Rowhammer would qualify as a bigger problem, yes.
