Olá pessoal, já resolvi fazendo dessa forma:


-- 1 - Creating the Sequence:

    CREATE SEQUENCE users_code_seq
    INCREMENT 1
    MINVALUE 1
    MAXVALUE 9223372036854775807
    START 1000;
    CACHE 1;

-- 2 - Setting the DEFAULT

    ALTER TABLE public.users ALTER COLUMN code SET DEFAULT
NEXTVAL('users_code_seq');

-- 3 - Setting the column as NOT NULL;

    ALTER TABLE public.users ALTER COLUMN code SET NOT NULL;

-- 4 - Creating a CONSTRAINT UNIQUE
        ALTER TABLE public.users
          ADD CONSTRAINT uc_users_code UNIQUE("code");


Obrigado
