Table X its full, what can i do now?

Hi everyone,

I have the following sql script:

CREATE SEQUENCE "public"."teste_seq"
INCREMENT 1 MINVALUE 1
MAXVALUE 32767 START 1
CACHE 1 CYCLE;

CREATE TABLE "public"."teste" (
"id" SMALLINT DEFAULT nextval('teste_seq'::regclass) NOT NULL,
CONSTRAINT "id_pk" PRIMARY KEY("id")
) WITHOUT OIDS;

for($i=1;$i<32767;$i++)
{
$sql = "insert into teste values(DEFAULT)";
echo pg_query($sql);
}
$sql = "delete from teste where id=5";
pg_query($sql);
$sql = "delete from teste where id=10";
pg_query($sql);
$sql = "delete from teste where id=51";
pg_query($sql);
$sql = "delete from teste where id=35";
pg_query($sql);
$sql = "delete from teste where id=125";
pg_query($sql);
$sql = "delete from teste where id=425";
pg_query($sql);
The table teste its full but it has some holes, i can´t insert no
more, it give´s me the error: duplicate key violates unique constraint
"id_pk".
What can i do to be able to continue inserting rows on this table?

Thanks a lot.
