In principle it could be backpatched, because this is just a change in
the search behavior and not a change in either catalog entries or rtree
index contents; hence no initdb needed. However, given that the
behavior has been broken since the rtree code was written and nobody
noticed except bwhite, I think it's pretty low-priority to back-patch.
I find it more significant for 8.1 because (a) it's now more likely that
indexscans will get used for these queries, and (b) I'm thinking we
really ought to fold rtree_gist into the core so that we have at least
some built-in gist opclasses (for testing purposes if nothing else).
I started out looking for the bug in rtree_gist, and eventually realized
that it had slavishly copied rtree's bug...
