There is no easy tool to do that right now. You will have to use
ST_MapAlgebraFct and write your own custom function. Let us know your

Unfortunately I couldn't find a successful solution to do a Euclidean
distance raster so being pushed for time on my dissertation, I made one in
ArcGIS and used it for the next stage. I am trying to recreate a ArcGIS
tutorial using PostGIS, starting with the same data for both and examining
