[postgis-users] NoDataValue

[Paolo Cavallini]

Hi all.
If I
SELECT nodata_values
from raster_columns
where r_table_name='basin_toscana';

 nodata_values
---------------

(1 riga)

then

UPDATE basin_toscana
SET rast = ST_SetBandNoDataValue(rast,1, 65535);

why I still get:

SELECT nodata_values
from raster_columns
where r_table_name='basin_toscana';

 nodata_values
---------------

(1 riga)
?

Also, I get:

SELECT srid from raster_columns where r_table_name='basin_toscana';
 srid
------
    0
(1 riga)

in spite of having imported with

raster2pgsql -s 3003 -I -M basin_toscana.tif > basin.sql

Thanks for any hint.
All the best.
