It sounds like between you both you've come up with a pretty solid
argument by exclusion for throttling WAL writing as space grows
critical. Dropping archive segments seems pretty unsafe from the solid
arguments Daniel presents, and Josh makes a good case for why shutting
the DB down when archiving can't keep up isn't any better.
