    v118 v119  
    174174  -Both rasters values when they are both nodata (nodatanodataexpr in the functions below)
    175175
    176  Open Question 1:
    177       DZ: Should ST_MapAlgebra resample the resulting rasters internally, or should we let the users resample it afterward with ST_Resample:
    178   ST_Resample(ST_MapAlgebra(), originx, originy, pixelsizex, pixelsizey)[[BR]]
    179         PR: I think this would greatly contribute to simplify the API.
