Why? If we're not talking hardware damage and you have a dump made sometime
previous to the crash, why wouldn't that work to restore the database? I've
had to restore a corrupted database from a dump before, there wasn't any
hardware damage, the database (more specifically the indexes) were
corrupted. Of course WAL wasn't around but I don't see why this wouldn't
work...
Note I'm not saying you're wrong, just asking that you explain your comment
a little more. If WAL can't be used to help recover from crashes where
database corruption occurs, what good is it?
