+1 to all of these.  Will send extremely short doc patch tonight.  I
recommend we create
http://wiki.postgresql.org/wiki/PostgreSQL_8.5_Open_Items and start
bumping things that can't be completed for 8.4.

Basically, my opinion is that if it's not a regression, it's too late
to work on it now.  We should ship the release when we're confident
that the new features have had adequate testing and we've squashed all
the regressions.
