WITH max_ordering AS ( SELECT MAX(ordering) as max_ordering FROM chill_main_civility )
INSERT INTO chill_main_civility (id, name, abbreviation, active, ordering)
    SELECT nextval('chill_main_civility_id_seq'),
        t.civility1, t.civility1, true,
        max_ordering.max_ordering + row_number() OVER () as ordering
    FROM ( SELECT DISTINCT ON (civility) civility1 FROM import.choix_personnes WHERE civility1 IS NOT NULL ) t
    CROSS JOIN max_ordering
    WHERE NOT EXISTS ( SELECT 1 FROM chill_main_civility WHERE name::jsonb = t.civility1 );
