btree_gist is essentially required for exclusion constraints to be
useful in a practical way.
In fact, can you submit it for the next commitfest to be included in
core? That would allow range types and exclusion constraints to be used
out-of-the-box in 9.2.
Only if you think it's reasonable to put it in core, of course. If
extensions are easy enough to install, maybe that's not really
necessary.
