[postgis-users] Problem using ST_MapAlgebraExpr (II)

[DavidRA]

Hi again, when developing other functions I encountered a new problem with
the 2 raster band version of ST_MapAlgebraExpr(). First of all, this is the
function (it calculates the ordered weighted average out of two rasters):




Then, I try to execute it like this:



but I get this error:



Invalid pixel type? I'm using the same maps than before and the structure of
the function is quite similar... but I didn't get this error with the
normalize function nor others.
