BUG #3224: Dump: missing schema name for sequence in a "DEFAULT nextval" specification

The following bug has been logged online:

Bug reference:      3224

Description:        Dump: missing schema name for sequence in a "DEFAULT
nextval" specification
Details:

Here is the example. I have a schema called 'dimensions' where I have a
hosts_2006_seq sequence and a hosts_2006 table, defined as follows:

CREATE SCHEMA dimensions;
CREATE SEQUENCE dimensions.hosts_2006_seq;
CREATE TABLE dimensions.hosts_2006
(
  id_host integer NOT NULL DEFAULT
nextval('dimensions.hosts_2006_seq'::regclass),
  host character varying(255) NOT NULL DEFAULT ''::character varying,
  CONSTRAINT hosts_2006_pkey PRIMARY KEY (id_host)
);

As you can see I want the 'nextval' function to get the sequence value from
the proper table in the 'dimensions' schema, and that works fine.

However, when I issue a pg_dump or pg_dumpall command, here is what I get:

SET search_path = dimensions, pg_catalog;
CREATE SEQUENCE hosts_2006_seq;
CREATE TABLE hosts_2006 (
    id_host integer DEFAULT nextval('hosts_2006_seq'::regclass) NOT NULL,
    host character varying(255) DEFAULT ''::character varying NOT NULL,
);

This causes the 'nextval()' to go and look for the proper sequence according
to the search path and not in  an absolute way.

I don't know whether this can be considered a bug, but it definitely created
a few problems on my scenario.

Thank you.
