Description
Low range pixel type band should be converted to higher range one when processing a multiple band raster. For example, doing:
C:\Windows\System32>gdal_translate -oF GTiff "PG:host='localhost' dbname='test3' user='postgres' password='1postgres' ta ble='test09_3'" c:/temp/test09_3-mode1.tif
on this table:
CREATE TABLE test09_3 AS SELECT 1 rid, ST_AddBand(ST_AddBand(ST_MakeEmptyRaster(10, 10, 0, 0, 0.1, 0.1, 0, 0, 4269), '8BUI'::text, 1, 0), '32BSI'::text, 2, 1) rast;
results in a raster having two 8 bit bands. A clever choice would be to convert the first band to 32 bit, not the opposite. The rule should be convert everything to the pixel type having the broadest range of values.
