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)
