No objections with adding a long option for that stuff. But I do have
an objection with the naming because we have another tool able to work
on relfilenodes:
$ oid2name --help | grep FILE
-f, --filenode=FILENODE show info for table with given file node

In this case, long options are new as of 1aaf532 which is recent, but
-f is around for a much longer time.

Perhaps we should use the same mapping for consistency?
pg_verify_checksums has been using -r for whatever reason, but as we
do a renaming of the binary for v12 we could just fix that
inconsistency as well. Hence I would suggest that for the option
description:
"-f, --filenode=FILENODE"

I would also switch to the long option name in the tests at the same
time, this makes the perl scripts easier to follow.
