Description

DISTINCTPC, DISTINCTPCSA, and NDV_NO_FINALIZE were most likely added as a means to implement other functionality (compute stats?) and probably not intended for general use. If possible those functions should be hidden so users don't rely on them (and Impala is able to redefine them as needed).
