I think it is in the respective pages of those operations. Forex. the information about parallel vacuum can be found in the Vacuum page [1]. > If nobody hasn't started making this kind of modifications, can we deter it > after the feature freeze?

I think you have a valid point but maybe it would be better to do the improvements you are suggesting once the parallel inserts related work is committed.
