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. -- Michael
