So put it in the next commitfest.

FWIW, I looked at this last week, and concluded I didn't have enough
confidence in it to push it into 9.2 at the last minute.

There's also the big-picture question of whether we should just get rid
of fuzzy comparisons in the geometric types instead of trying to hack
indexes to work around them. I'd really rather have us debate that
question and resolve it one way or the other before spending time on the
details of patches that take the second approach.
