The newest release of pgBackRest (http://www.pgbackrest.org) will
validate all data checksums whenever doing a backup.  Invalid checksums
are reported in the backup log and recorded in the backup manifest.

The functionality requires a companion library that has not made it into
the community Debian/RHEL packages yet, but should be available soon.
