tfloat_arithop_turnpt() int tfloat_arithop_turnpt ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, Datum param  UNUSED, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Find the single timestamptz at which the operation of two temporal float segments is at a local minimum/maximum. The function supposes that the instants are synchronized, that is, start1->t = start2->t and end1->t = end2->t. The function only return an intersection at the middle, that is, it it returns false if the timestamp found is not at a bound Note This function is called only when both sequences are linear
