Someone (Tom?) mentioned upthread that if we wanted to do cleanup it
should be more than just one GUC, and I agree with that, and I'm willing
to investigate when the current compat GUCs went in and create a patch
to remove the really old ones. My inclination would be to just do this
as part of 10.0. (And I agree with Robert's comments about parallel
being the most likely driver for bumping to 10.0).
