INSERT FOLLOW WITH OTHER INSERT - Mailing list pgsql-sql

hi all

i have a table like this 

CREATE SEQUENCE seq_student_id INCREMENT 1 START 1;
CREATE TABLE students ( student_id INT4 NOT NULL DEFAULT
NEXTVAL('seq_student_id'), student_name text, student_address text, primary key(student_id)
)
CREATE TABLE student_club ( student_id INT4 NOT NULL; club_id INT4, CONSTRAINT student_id_update FOREIGN
KEY(student_id)
REFERENCES students(student_id) ON UPDATE CASCADE
)

my question is how i can make auto insert student_id
on table student_club when i insert into table
students

example:
INSERT INTO students(student_name) VALUES('Willy');

table STUDENT
student_id | name    | address
---------------------------------
1          | Willy    |

and on TABLE student_club
student_id | club_id
--------------------
1          |


i have trying with create rule and with
check_foreign_key, but i haven't found solution.
anyone can help me?

Thanks in advance
