tpoint_geo_distance_turnpt() static int tpoint_geo_distance_turnpt ( Datum  start, Datum  end, Datum  point, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) static Return 1 or 2 if a temporal point segment and a point are at a minimum distance during the period defined by the output timestamps, return 0 otherwise. These are the turning points when computing the temporal distance. Parameters [in] start,end Values defining the first segment [in] point Point to locate [in] lower,upper Minimum distance at turning point [out] t1,t2 Timestamps defining the resulting period, may be equal Precondition The segment is not constant Postcondition As there is a single turning point, t2 is set to t1
