As Richard suggested, use TRIGGER instead RULE, but okay.

A little example, i hope, it helps:
(2 little tables t1 and t2 and a UPDATE-RULE on t1 with a 'do also')

test=# create table t1 (id int, val int);
CREATE TABLE
test=*# create table t2 (id int, val int);
CREATE TABLE
test=*# create rule r1 as on update to t1 do also update t2 set val =
new.val where id=new.id;
CREATE RULE
test=*# commit;
COMMIT
test=# insert into t1 values (1,1);
INSERT 0 1
test=*# insert into t1 values (2,2);
INSERT 0 1
test=*# insert into t2 values (1,1);
INSERT 0 1
test=*# insert into t2 values (2,2);
INSERT 0 1
test=*# update t1 set val =10 where id=1;
UPDATE 1
test=*# select * from t2;
id | val
----+-----
2 | 2
1 | 10
(2 rows)
