postgresql schema has leftover zones sequence (should be cells now)

Using Nova w/ PostgreSQL. It looks like we have a leftover zones sequence that needs to be renamed to its 'cell' equivalent:

--
-- Name: zones_id_seq; Type: SEQUENCE; Schema: public;
--

CREATE SEQUENCE zones_id_seq
    START WITH 1
    INCREMENT BY 1
    NO MINVALUE
    NO MAXVALUE
    CACHE 1;

ALTER TABLE public.zones_id_seq

--
-- Name: zones_id_seq; Type: SEQUENCE OWNED BY; Schema: public;
--

ALTER SEQUENCE zones_id_seq OWNED BY cells.id;

--
-- Name: zones_id_seq; Type: SEQUENCE SET; Schema: public;
--

SELECT pg_catalog.setval('zones_id_seq', 1, false);

---------------------------

When renaming tables in our SQLAlchemy script we'll need to be mindful that this leaves behind orphaned sequences on PostgreSQL.
