Tom Lane 1da2a610d7 Back-patch recent fixes for gistchoose and gistRelocateBuildBuffersOnSplit.
This back-ports commits c8ba697a4b and
e5db11c558, which fix one definite and one
speculative bug in gistchoose, and make the code a lot more intelligible as
well.  In 9.2 only, this also affects the largely-copied-and-pasted logic
in gistRelocateBuildBuffersOnSplit.

The impact of the bugs was that the functions might make poor decisions
as to which index tree branch to push a new entry down into, resulting in
GiST index bloat and poor performance.  The fixes rectify these decisions
for future insertions, but a REINDEX would be needed to clean up any
existing index bloat.
