Is there any way around that? If WAL can't be trusted that means if you
crash during update, you're hosed. Which means you need to backup the
database before upgrading, which greatly increases downtime. Same
applies to having to reindex everything.
Granted, *any* kind of upgrade not requiring a dump/restore is a major
improvement.
