temporal_tagg_combinefn() SkipList * temporal_tagg_combinefn ( SkipList *  state1, SkipList *  state2, datum_func2  func, bool  crossings  ) Generic combine function for aggregating temporal values. Parameters [in] state1,state2 State values [in] func Aggregate function [in] crossings True if turning points are added in the segments Note This function is called for aggregating temporal points and thus after checking the dimensionality and the SRID of the values
