I'd just like to point out that Warren is a mate of mine :)
I recall a time when a related issue occurred years ago:
http://groups-beta.google.com/group/comp.databases.postgresql.hackers/browse_thread/thread/c97c853f640b9ac1/d6bc3c75eed6c2a4?q=could+not+access+status+of+transaction#d6bc3c75eed6c2a4
Not sure if it's a similar problem?
