The last time we had the idea to use _verify_ in a tool name, the same
tool has been renamed one year after as we found new use cases for
it, aka pg_checksums. Cannot the same be said with pg_validatebackup?
It seems to me that it could be interesting for some users to build a
manifest after a backup is taken, using something like a --build
option with pg_validatebackup.
