INT8 sequences - Mailing list pgsql-sql

Is it true that PostgreSQL sequences are always INT4?  If so, how
would the following be modified to work as obviously intended?

CREATE SEQUENCE tbl_id INCREMENT 1 START 1;
CREATE TABLE tbl
(       id              INT8 DEFAULT NEXTVAL('tbl_id') PRIMARY KEY
);

Thanks.
