Why some optimizer features are available in Oracle 8.0 and 9 but not in 8.1?

Hi everyone,



Does anyone know why some optimizer features like 'complex view merging' or 'push-join predicate' are available for Oracle 8.0 and 9 but not for 8.1?
Additional question (the answer is probably no but...) : is there a way to get them in 8.1 ?



Thanks
