That message can be safely ignored assuming you're not getting any
error messages preceding it. The message itself indicates that the band
had no values worth counting...

Hi,
I do this query for counting the frequency of values in a raster:
SELECT identifian, ST_ValueCount(ST_Clip(rast, geom)) As pvc
FROM raster400x400_out, zones
WHERE ST_Intersects(rast, geom)
and I get many message like:
"Unable to count the values for band at index 1"
What does that mean?
