Previously, some functions returned various fixed strings and others failed with a cache lookup error. Per discussion, standardize on returning NULL. Although user-exposed "cache lookup failed" error messages might normally qualify for bug-fix treatment, no back-patch; the risk of breaking user code which is accustomed to the current behavior seems too high.
