But segments are created when new data is loaded. Therefore metadata for all the paritions should be there to create segment when the data for that partition is loaded. It is about what you consider as "metadata" - that is meta metadata!. About Interval parition, We are not going to see all the possible partitions (1 million?) created in the Oracle views.
