In discussion a question arose. I don't think we currently compare these
columns before when we're building an index and find a visible hot update. We
just set hot_visible even if the chain might still be a valid hot chain for
the new index right? Should we consider checking the columns in that case too?
Or would it be too much extra overhead?
