Huh?
More precise: what I mean here is that should an OS crash or a power
failure happen, we would fall back to recovery at next restart, so we
would not actually *lose* data.
Except that we actually can't perform the recovery properly because we
may not have the last WAL segment (or multiple segments), so we can't
replay the last batch of transactions. And we don't even notice that.
