Comment(by pracine):

 I don't understand what is the advantage of having an extra argument for
 nodata value over supporting "NULL" in reclassexpr. e.g.

 ST_Reclass(rast, 1, '0-100:1-10, 101-500:11-150,501 - 10000: 151-254, 255:
 NULL', '8BUI')

 instead of:

 ST_Reclass(rast, 1, '0-100:1-10, 101-500:11-150,501 - 10000: 151-254',
 '8BUI', 255)
