tsegment_intersection() int tsegment_intersection ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, meosType  temptype, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return 1 or 2 if two temporal segments intersect during the period defined by the output timestamps, return 0 otherwise. Parameters [in] start1,end1 Base values defining the first segment [in] start2,end2 Base values defining the second segment [in] temptype Temporal type [in] lower,upper Timestampts defining the segments [out] t1,t2 Timestamps defining the resulting period, may be equal Precondition The instants are synchronized
