Hi Hiroshi-san,

if you want you can include the function we have used to test the problem,
pasted below.

CREATE OR REPLACE FUNCTION test_uuidgen(countmax INTEGER) RETURNS character
varying AS
$BODY$
DECLARE
  countmin INTEGER := 1;
  distinctuuid bigint;
  v_message VARCHAR(2000) := '';

BEGIN
    drop table if exists uuid_gen;
    CREATE TABLE uuid_gen
    (
      uuid_gen_col uuid NOT NULL

    );
    LOOP
        INSERT INTO uuid_gen (uuid_gen_col) VALUES (uuid_generate_v1());
        countmin := countmin + 1;
        EXIT WHEN countmin > countmax;
    END LOOP;
    SELECT COUNT(DISTINCT uuid_gen_col) INTO distinctuuid FROM uuid_gen;
    IF distinctuuid <> countmax THEN
        v_message := 'Repeated UUID: FAILS';
    ELSE
        v_message := 'NO repeated UUID: OK';
    END IF;
    RETURN v_message;
