restoring a backup and maintaining dependencies?

Hi again :)

I have saved out these commands:

CREATE TABLE group_items
(
id serial NOT NULL,
group_id integer,
group_type text,
item_id integer,
visible integer,
CONSTRAINT "group_items_PK" PRIMARY KEY (id)
)
WITHOUT OIDS;
ALTER TABLE group_items OWNER TO postgres;

CREATE SEQUENCE group_items_id_seq
INCREMENT 1
MINVALUE 1
MAXVALUE 9223372036854775807
START 1
CACHE 1;
ALTER TABLE group_items_id_seq OWNER TO postgres;

If I restore them in pgadmin will they become dependent on each other in
the same way as if I created the table in pgadmin? Or will they just
become separate entities without any form of link? If that IS the case,
how can I link them with SQL code, rather than pgadmin?

Advice appreciated lots, I have a lot to learn here :|
