tpoint_geo_bearing_turnpt() static int tpoint_geo_bearing_turnpt ( Datum  start, Datum  end, Datum  point, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) static Return the value and timestamptz at which the a temporal point segment and a point are at the minimum bearing. Parameters [in] start,end Values defining the segment [in] point Geometric/geography point to locate [in] lower,upper Timestampts defining the segment [out] t1,t2 Precondition The segment is not constant and has linear interpolation Postcondition As there is a single turning point, t2 is set to t1
