If it becomes easier to build a simple tool available to help people tune
their configurations, that should help here without having to do anything
more complicated than that.

Like some of the other GUC simplification ideas that show up sometimes
(unifying all I/O and limiting background processes based on that total is
another), this is hard to do internally. Josh's proposal has a fair
amount of work involved, but the code itself doesn't need to be clever or
too intrusive. Unifying all the memory settings would require being both
clever and intrusive, and I doubt you'll find anybody who could pull it
off who isn't already overtasked with more important improvements for the
8.4 timeframe.
