sequence... my nightmare :-(

Hi,

i have a schema called : test_survey
i have within this schema this table:
CREATE TABLE test_survey.accounts
(
"ID" bigint NOT NULL DEFAULT
nextval('test_survey."accounts_ID_seq"'::regclass),
"login" character varying(300) NOT NULL,
pwd character varying(100) NOT NULL,
creation_date timestamp without time zone NOT NULL,
CONSTRAINT accounts_pkey PRIMARY KEY ("ID")
)
WITH (OIDS=FALSE);
ALTER TABLE test_survey.accounts OWNER TO mysurvey;

and this sequence:
CREATE SEQUENCE test_survey."accounts_ID_seq"
INCREMENT 1
MINVALUE 1
MAXVALUE 9223372036854775807
START 1
CACHE 1;
ALTER TABLE test_survey."accounts_ID_seq" OWNER TO mysurvey;

when i write the following query i get the error :ERROR: relation
"accounts_id_seq" does not exist
SET search_path = test_survey;
insert into accounts values
(nextval('accounts_ID_seq'),'test(at)test(dot)com','ab4ef51934f2d3f02f1a','11/19/2007
15:46:09');

why ?
