There is a trigger on that table, and it is certainly the culprit as
can be seen here (different table, same trigger):

I don't think the committed patch touches anything involved in what
you're testing, but if you could grab CVS tip from the 8.4 branch (or
the snapshot from ftp.postgresql.org:/pub/snapshot/stable/8.4 ) and give
it a try, that'd be great.

I trigger the same error with a freshly built snapshot.
