tcbuffer_tcbuffer_distance_turnpt() int tcbuffer_tcbuffer_distance_turnpt ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, Datum param  UNUSED, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return 1 or 2 if two temporal circular buffers segments are at a minimum distance during the periods defined by the output timestamps, return 0 otherwise. These are the turning points when computing the temporal distance. Parameters [in] start1,end1 Instants defining the first segment [in] start2,end2 Instants defining the second segment [in] param Additional parameter [in] lower,upper Minimum distances at turning points [out] t1,t2 Timestamps defining the resulting period, may be equal
