Your use of parentheses in the SELECT targetlist is incorrect (and would
be with or without the RULE context). What this is trying to do is
insert a single composite column into the target table. You want
INSERT INTO b.iteration(id,date_period_begin)
SELECT NEW.id,NEW.date_period_begin FROM a.iteration;
