tfloat_distance_turnpt() int tfloat_distance_turnpt ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, Datum param  UNUSED, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return 1 if two temporal number segments intersect during the period defined by the output timestampts, return 0 otherwise. Parameters [in] start1,end1 Values defining the first segment [in] start2,end2 Values defining the second segment [in] param Additional parameter [in] lower,upper Timestamps defining the segment [out] t1,t2 Timestamps defining the resulting period, may be equal Note This function is passed to the lifting infrastructure when computing the temporal distance Postcondition As there is a single turning point, t2 is set to t1
