The following indexes are missing from the database and should be recreated: index_collection_items_on_uri, index_collections_on_uri, index_email_subscriptions_on_account_id_and_email, index_email_subscriptions_on_account_id, index_email_subscriptions_on_confirmation_token, index_keypairs_on_account_id, index_keypairs_on_uri, index_tagged_objects_on_object, idx_on_status_id_object_type_object_id_d6ebe374bd, index_tagged_objects_on_status_id_and_uri. Missing indexes may lead to severely reduced performance and data inconsistencies.
