Attached.  Passes all the usual regression tests I run, plus light
ad hoc testing.  All is working fine as far as this patch itself
goes, although more testing is needed to really call it sound.

If anyone is interested in the differential from version 3 of the
patch, it is the result of these two commits to my local repo:

http://git.postgresql.org/gitweb?p=users/kgrittn/postgres.git;a=commitdiff;h=018b0fcbeba05317ba7066e552efe9a04e6890d9

During testing I found two annoying things not caused by this patch
which should probably be addressed in 9.1 if feasible, although I
don't think they rise to the level of blockers.  More on those in
separate threads.
