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');
