Yes, of course we can solve this by restoring from backup.
But if the database volumn is large, say, 100TB or more, the cost
is really too expensive just because the tiny clog file corrupt.
Why would you trust the other 99.999 TB if something corrupted the clog

system has
been compromised, so you restore from backup with WAL replay.
