My dim recollection was that the underlying problem was that a table had been renamed
(bad order of operations!!), damaging one or more foreign key links.  I was able to
fix it by editing a pg_dump'ed version of the database, and restoring the database
from the dump, thereby repairing the FK links.

Your problem may be different!
