Sounds great! Thank you.

The repo is available here:


I'd prefer to include it in the initial patch. If the current GiST code
is going to be replaced, then there's not much sense reviewing/testing

You may need to consider unbounded and empty ranges specially. I made an
attempt to do so in the current GiST code, and you might want to take a
look at that first. I'm not particularly attached to my approach, but we
should do something reasonable with unbounded and empty ranges.
