I proposed something similar for pg_basebackup back then and IIRC Peter
(rightfully) complained that using a system catalog for that wasn't so
great - also, are you sure the relfilenode will always be stable? Then
again, this is obviously a throw-away data directory so it should be no
general issue, just a matter of taste.
https://github.com/credativ/pg_checksums/blob/master/t/001_checksums.pl
has some similar tests at the end but creates a table for corruption,
adds some safeguards for block size and also uses command_checks_all()
to parse the output. It's PGDG licensed so you're welcome to take some
or all of that.
