ST_DumpValues should return an empty array when passed an empty raster

Description

SELECT (ST_DumpValues(ST_AddBand(ST_MakeEmptyRaster(0, 0, 0, 0, 1), ARRAY[ROW(NULL, '8BUI', 255, 0),ROW(NULL, '16BUI', 1, 2)]::addbandarg[]))).*

should return one row per band with the number of the band and an empty array for the values. Right now it just return nothing.

It is normal though that it returns nothing when there is no band:

SELECT (ST_DumpValues(ST_MakeEmptyRaster(10, 10, 0, 0, 1))).*
