Reverse engineered Column definition incorrect for DEFAULT

The reverse engineered code for column definitions if incorrect for DEFAULT values.
I create table such as:

REATE TABLE public.tbl_bkgndata
(
id int4 NOT NULL DEFAULT nextval('tbl_bkgndata_id_seq'::text),
) WITHOUT OIDS;

Reverse engineered column definition is:

ALTER TABLE public.tbl_bkgndata ADD COLUMN id int4;
ALTER TABLE public.tbl_bkgndata ALTER COLUMN id SET STORAGE PLAIN;
ALTER TABLE public.tbl_bkgndata ALTER COLUMN id SET NOT NULL;
ALTER TABLE public.tbl_bkgndata ALTER COLUMN id DEFAULT nextval('tbl_bkgndata_id_seq'::text);

Last row should read:
ALTER TABLE public.tbl_bkgndata ALTER COLUMN id SET DEFAULT nextval('tbl_bkgndata_id_seq'::text);

That is the key word SET is missing.
