This is no longer true for GIST, and hash really ought to be fixed to
support WAL. The combination of a performance advantage and being able
to postpone fixing hash might be enough of a reason to add a
post-recovery index rebuild feature, but I don't think the latter
alone is --- fixing hash would be less work as well as being the "right"
answer.
