Comment(by pracine):

 Replying to [comment:10 dustymugs]:
 > Looking at the variant taking values from a second raster in the plpgsql
 prototype, I had a question.  Is the second raster a simple data source
 since there is no validation of pixel types, SRID, width, height?

 This variant works in world coordinate so if the SRID, the width, the
 height are different it should not matter. In the worst case nothing is
 copied. If the pixel type are different, the source value should be casted
 to the destination pixel type.

 This variant will be, with ST_AddBand(from another raster), our only way
 to copy values from another raster.
