syntax error with example sql of createtable

Hello,

I got a error when execute below command in
  http://developer.postgresql.org/docs/postgres/sql-createtable.html

postgres=#  CREATE TABLE array (vector  int[][]);
ERROR:  syntax error at or near "array" at character 14
LINE 1: CREATE TABLE array (vector  int[][]);

                     ^
(I tried it on 8.0.0rc2.)

'array' is a reserved word, so it needs quote to create table
named array:
postgres=#  CREATE TABLE "array" (vector  int[][]);
CREATE TABLE
