James 179a7eed38 Added explicit null value information ... When updating a row with a large text column, but the large column's value is unchanged, decoderbufs won't send the value of the column to the logical subscriber. However, the subscriber has no way to detect whether the column was left untouched or deliberately given a null value. Adding explicit null value information on each datum should rectify this situation.		2019-06-26 22:06:00 +07:00
