No, I mean it it would be great if we did not need to materialise whole DB 
anywhere. Let's say I have a backup of 10Tb cluster in S3. And don't have that 
clusters hardware anymore. I want to spawn tiny VM with few GiBs of RAM and 
storage no larger than biggest index within DB + WAL from start to end. And 
stream-check all backup, mark it safe and sleep well. It would be perfect if we 
could do backup verification at cost of corruption monitoring (and not vice 
versa, which is trivial).
