Well, it tries --- there is logic in there that pays attention to the
scan direction. Like I say, I don't know the extent of the difficulty.
If we were to decide that it's unfixable, the right thing would be to
have the planner stick a materialize node on top, rather than invent
a specialized kluge for GIST.
