You need to explicitly update the row because changes to the OLD
reference will be lost, for instance:
CREATE or replace FUNCTION person_fake_delete() RETURNS TRIGGER AS ' BEGIN UPDATE your_table SET status = 1
WHEREprimary_key = OLD.primary_key; RETURN NULL; -- I thought this would prevent the delete from actually
happening. END;
' LANGUAGE 'plpgsql';

Really?, The tuple is still deleted? There should be something that you are
not telling us (may be you are creating the trigger to run AFTER instead of
BEFORE). It have worked for me in each version since the trigger system
were added to postgres.
