Yes. And the main use case for the index on (extoid) is listing a given
extension's features, that we want to order by their name, then the set
of indexes I've been defining is now:
Indexes: "pg_extension_feature_name_index" UNIQUE, btree (extfeature) "pg_extension_feature_oid_index" UNIQUE,
btree(oid) "pg_extension_feature_extoid_name_index" btree (extoid, extfeature)
