I'm glad that was inspirational for you. Not to nit pick, but my
trigger based version did in fact track deletions:
CREATE TRIGGER audit_$$ || sch || $$_$$ || tbl || $$_update_trigger
AFTER UPDATE OR DELETE ON $$ || sch || $$.$$ || tbl || $$ FOR EACH ROW
^^^^^^^
EXECUTE PROCEDURE auditor.audit_$$ || sch || $$_$$ || tbl || $$_func ();
You may want to consider using the LIKE style of table copying, as it
strips all constraints from the new table. It's safer IMHO, as this
way you wouldn't have to worry about the primary key being propagated
to the new table (and accidentally forgetting to remove it).
