La distribution de PostgreSQL inclut les classes d'opérateur GiST indiquées dans Tableau 65.1. (Quelques modules optionnels décrits dans Annexe F fournissent des classes d'opérateur GiST supplémentaires.)

Pour des raisons historiques, la classe d'opérateurs inet_ops
n'est pas la classe par défaut pour les types inet et
cidr. Pour l'utiliser, mentionnez le nom de la classe dans la
commande CREATE INDEX, par exemple
CREATE INDEX ON ma_table USING GIST (ma_colonne_inet inet_ops);
