it appears I have a broken RI in my db.

call_individual.clh_id references call_household.clh_id

\d call_individual
...
Foreign-key constraints:   "call_individual_clh_id_fkey" FOREIGN KEY (clh_id) REFERENCES
call_household(clh_id) ON DELETE CASCADE

however:
development=# select clh_id from call_individual cli where not exists(
select 1 from call_household clh where clh.clh_id=cli.clh_id );clh_id 
-------- 14691

should not matter, but call_individual has a pre-delete trigger that
simply raises an exception to prevent deletions:       raise exception 'calls may not be deleted';
