How to make a non-removable row in a table?

Hi all.

How to make a non-removable row in a table?

In my case, I should not accidentally delete a row with id = 0.

CREATE TABLE profile (

id integer NOT NULL,

name character varying(265) NOT NULL

);

CREATE SEQUENCE profile_id_seq
START WITH 1
INCREMENT BY 1
NO MAXVALUE
NO MINVALUE
CACHE 1;

ALTER TABLE profile ALTER COLUMN id SET DEFAULT
nextval('profile_id_seq'::regclass);

ALTER TABLE ONLY profile ADD CONSTRAINT profile_pkey PRIMARY KEY (id);

INSERT INTO profile VALUES (0,'non-removable Profile');
