Copy and serial type problem

Hi,

I've created a small table:

CREATE TABLE "table" (
"id" int4 DEFAULT nextval('"table_idd_seq"') NOT NULL,
"file" character varying(40) NOT NULL
);

Table sequence 'table_idd_seq' is also available with a next id number.

Question is how to use postgres copy function with this 'id'. Table 'table'
is not empty... I've tried to insert nextval("table_idd_seq") into file but
it doesn't work.

Any help would be appreciated.

TIA
