tcbuffersegm_intersection() int tcbuffersegm_intersection ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return 1 if the segments of two temporal circular buffers intersect during the period defined by the timestamps output in the last arguments. Parameters [in] start1,end1 Temporal instants defining the first segment [in] start2,end2 Temporal instants defining the second segment [in] lower,upper Timestamps defining the segments [out] t1,t2 Returns Number of timestamps in the result, between 0 and 2. In the case of a single result both t1 and t2 are set to the unique timestamp
