Thanks! I will take a look.

See here and following for some of the previous discussion - which was
not unanimous on all points:
http://archives.postgresql.org/pgsql-hackers/2009-09/msg00139.php
I think the intention is not to accept only bug fixes, but to limit
large features to those that have already been through a CommitFest or
two.

I'm not sure. One of the problems with separating out contrib module
changes is that it tends to obscure the point of the changes to the
core code. On the other hand if some of the core code changes can be
split out into an infrastructure patch that is of some independent
usefulness, that can certainly be worthwhile. It's not obvious to me
without looking at this more than I have whether there is a possble
split that makes sense here; I will read your updated patch.
