vacuum code. After commit b61d161c14, during vacuum, we cache the information of relation name and relation namespace in local structure LVRelStats so that we can use it in an error callback function. We can use the cached information to avoid the calls to RelationGetRelationName(), RelationGetNamespace() and get_namespace_name(). This is mainly for the consistent in vacuum code path but it will avoid the extra syscache lookup we do in get_namespace_name().
