hm ... jsonb_full_ops seems nicely short, but on the other hand it just
begs the question "full what?".  I'm a bit worried about future-proof-ness
too; what if somebody later comes up with a new opclass that indexes more
operators?  We'd end up calling it jsonb_fuller_ops, ick.

I was kind of hoping for a technical adjective, like "hash" is for the
soon-to-be-default opclass.  What is it about this opclass that
distinguishes it from other indexing approaches that someone might try?
