You must be leaving something out of the story...

$ psql
Password:
Welcome to psql 7.4.2, the PostgreSQL interactive terminal.
...
jseymour=# create table student(
jseymour(# id SERIAL NOT NULL,
jseymour(# name VARCHAR(35) NOT NULL,
jseymour(# primary key (id)
jseymour(# );
NOTICE: CREATE TABLE will create implicit sequence "student_id_seq"
for "serial" column "student.id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"student_pkey" for table "student"
CREATE TABLE
jseymour=# insert into student (name) values('me');
INSERT 8776502 1
jseymour=# insert into student (name) values('me');
INSERT 8776503 1
jseymour=# insert into student (name) values('me');
INSERT 8776504 1
jseymour=# select * from student;
id | name
----+------
1 | me
2 | me
3 | me
(3 rows)

Seems to work here.
