what is wrong with this SQL?

create table USERS (
ID decimal(19) CONSTRAINT primary_usr_oid PRIMARY KEY,
WRITE_COUNT decimal(19) NOT NULL,
CLASS decimal(10) NOT NULL,
STATUS decimal(3) NOT NULL,
USR_LOGIN_USER_ID varchar2(16) ,
USR_PASSWORD varchar2(16) ,
USR_PERSON_FIRST_NAME varchar(32) ,
USR_PERSON_MIDDLE_NAME varchar(32) ,
USR_PERSON_LAST_NAME varchar(32) ,
USR_PERSON_SALUTATION varchar(32) ,
USR_PERSON_SUFFIX varchar(32)
);

when i am in psql and i do: \i createUsersTable.sql i get this error:
psql:createUsersTable.sql:13: ERROR: parser: parse error at or near "("

What is this?
