current GiST lacks of concurrency and recovery support. It's doable and
there are some plans (me and Teodor) to work on it, but we still have no
time. That means, it's too early to integrate gist based contribs into
core. Also, current GiST interface should be enhanced to be able support
some very interesting data types like digital trees, similarity tree, etc.
