Proposed patch attached.  The existing text already says "GIN indexes are
the preferred text search index type", so I'm not sure we need to go
further than that about guiding people which one to use.  In particular,
since GIN can't support included columns, we can't really deprecate GiST
altogether here.

Yeah, I was wondering about that too.  It's sort of the nuclear option,
but if we don't want to modify EOL'd versions then we may not have any
other way to keep Google from glomming onto them.
