FWIW, I still think that checksumming belongs in the filesystem, not 
PostgreSQL. If you go ahead with this anyway, at the very least I'd like 
to see some sort of a comparison with e.g btrfs. How do performance, 
error-detection rate, and behavior on error compare? Any other metrics 
that are relevant here?
