Description

Génère un script qui supprime toutes les clés non primaires et les index non uniques sur le schéma tiger et le schéma spécifié par l'utilisateur. Le schéma par défaut est tiger_data si aucun schéma n'est spécifié.

Ceci est utile pour minimiser le gonflement de l'index qui peut perturber le planificateur de requêtes ou prendre de l'espace inutilement. A utiliser en combinaison avec Install_Missing_Indexes pour ajouter uniquement les index utilisés par le géocodeur.

Disponibilité : 2.0.0
