Comment(by pracine):

 1) Could you do this to demonstrate that the stored raster was actually
 edited:

 SELECT ST_Value(rast, ST_Point(3427927.75, 5793243.95)) As val FROM
 dummy_rast

 then:

 SELECT ST_Value(ST_SetValue(rast, ST_Point(3427927.75, 5793243.95),50),
 ST_Point(3427927.75, 5793243.95)) As val FROM dummy_rast

 and then:

 SELECT ST_Value(rast, ST_Point(3427927.75, 5793243.95)) As val FROM
 dummy_rast

 2) Could you do this:

 SELECT ST_BandPixelType(rast) FROM dummy_rast

 I think you got twice the same result because the pixel value was actually
 not set because 50 is out of the possible value range for this band. Let
 see...
