This issue (as detailed in this post):
http://archives.postgresql.org/pgsql-hackers/2009-11/msg01871.php

is currently the only significant outstanding issue in my review of this
patch. I think we need to see more feedback on whether it is acceptable
to change the aggregate function API again (and if so, what to do with it)
before I can post a final review on this and mark it ready for committer
(or not).
