postgresql

I am trying to setup the postgres.

When I run

```
CREATE TABLE vhashes (
    id integer DEFAULT nextval('vhahsh_id_seq'::regclass) NOT NULL,
    input character varying(8),
    output character varying(40)
);
```

I get a 

```
********** Error **********

ERROR: relation "vhahsh_id_seq" does not exist
SQL state: 42P01
```

Also is that a typo vhahsh and it should be vhash ?
