I think you're misreading. It's the string being passed to nextval that is
being cast to text, not the return value.

John

CREATE TABLE x (
id integer DEFAULT nextval('"x_id_seq"'::text) NOT NULL,
name character varying(30) NOT NULL
);

Because that's the name of the sequence, not the value coming out of the sequence.

Of course, a bigger question is why the ::text cast is needed at all.
