Ah, thanks for the pointer. I'd just been trying to bisect where
between 8.4 and 9.0 it changed, but failed because early-9.0 versions
don't build at all with current bison :-(

Anyway, given that the example needs updating, how should we do that
exactly? Is it worth demonstrating both the behavior with RETURNING
and that without? If not, which one to show?
