Hello,

Ran into this little gem with a customer today:

This works:

create table foo (foo int not null, bar text);
create sequence foo_seq;
alter table foo alter column foo set default nextval('foo_seq');

pg_dump will correctly dump the table:

CREATE TABLE foo (
    foo integer DEFAULT nextval('foo_seq'::text) NOT NULL,
    bar text
);


--
-- TOC entry 3 (OID 107565218)
-- Name: foo_seq; Type: SEQUENCE; Schema: public; Owner: postgres
--

CREATE SEQUENCE foo_seq
    START 1
    INCREMENT 1
    MAXVALUE 9223372036854775807
    MINVALUE 1
    CACHE 1;

However if you do the following:

create table foo (foo serial not null, bar text);
create sequence foo_seq;
alter table foo alter column foo set default nextval('foo_seq');

pg_dump will give you the following:

CREATE TABLE foo (
    foo serial NOT NULL,
    bar text
);


--
-- TOC entry 3 (OID 107566148)
-- Name: foo_seq; Type: SEQUENCE; Schema: public; Owner: postgres
--

CREATE SEQUENCE foo_seq
    START 1
    INCREMENT 1
    MAXVALUE 9223372036854775807
    MINVALUE 1
    CACHE 1;

Which is wrong because we want the column foo to use a default of foo_seq
not foo_foo_seq.

Sincerely,

Joshua D. Drake
