"NEW" is a macro, not a variable. This rule will be expanded to
something like
INSERT INTO test2
(sum1, name2, id, id1) VALUES ('1', '2', NEXTVAL('"test1_id_seq"'::text),
nextval('"test2_id1_seq"'::text));
which means that nextval('test1_id_seq') is evaluated twice, once during
the rule and once during the actual insert into test1.
You can't do what you want with a rule; you'll need to use a
trigger instead.
