There's a bug since it should work for any number, but we've likely missed
something. I'm not sure why 2 references work, as I'd expect it to stop
working after 1 with the likely causes, but one of the constraint checks
is happening before the row is finished being updated.

I don't think it'll help for this case (since it revolved around multiple
tables), but could you try the patch from
 http://archives.postgresql.org/pgsql-bugs/2007-05/msg00177.php
to see if it helps this case?
