Yeah.  I'd say that intarray's attempt to override the default status of
the built-in gin opclass is simply a bad idea and should be removed.
It's not even documented that it does that (in fact I see no mention of
GIN at all in README.intarray :-(, so we have a documentation lack
here too).

Comments?
