YEAR, DECADE, CENTURY, or MILLENIUM fields, just as it always has done for other types of fields. The previous behavior seems to have been a hack to avoid defining bit-positions for all these field types in DTK_M() masks, rather than something that was really considered to be desired behavior. But there is room in the masks for these, and we really need to tighten up at least the behavior of DAY and YEAR fields to avoid unexpected behavior associated with the 8.4 changes to interpret ambiguous fields based on the interval qualifier (typmod) value. Per my example and proposed patch.
