This is not an actual fix, but an optimization, no?
UNIQUE_CHECK_SPECULATIVE is just used to optimize a couple of code
paths in the case of a insert conflicting during btree insertion..
In any case, at this point 9.5 is really aimed to be stabilized, so
targeting only master is a far saner approach IMO for this patch.
Pushing that in 9.5 a couple of months back may have given enough
reason to do so... But well life is life.
