[GENERAL] MySQL to Postgres question

[Edward Blake]

The table I have in MySQL is similar to below:

 0 SET FOREIGN_KEY_CHECKS=0;
 1 CREATE TABLE products (
 2     product_id integer(11) not null auto_increment,
 3     product_name varchar(255) not null,
 4     product_descrition varchar(255) not null,
 5     class_id integer(11) not null,
 6     subclass_id integer(11) not null,
 7     department_id integer(11) not null
 8     PRIMARY KEY (product_id),
 9     KEY class_id (class_id),
10     KEY subclass_id (subclass_id),
11     KEY department_id (department_id)
12 );

When I try and rewrite it as a Postgres statement (below), it fails at line
9.
 0 SET CONSTRAINTS ALL DEFERRED;
 1 CREATE TABLE products (
 2      product_id serial[11] not null,
 3      product_name varchar[255] not null,
 4      product_descrition varchar[255] not null,
 5      class_id integer[11] not null,
 6      subclass_id integer[11] not null,
 7      department_id integer[11] not null
 8      PRIMARY KEY (product_id),
 9      KEY class_id (class_id),
10      KEY subclass_id (subclass_id),
11      KEY department_id (department_id)
12 );

Any ideas?
