Comment(by pracine):

 There are three options here:

 1-We don't want NODATA pixels to be returned as polygons

 2-We want them to be returned but set to NULL

 3-We want them to be returned but set as the NODATA value (e.g. 0), not
 NULL

 Option 3 should be possible by deactivating the nodatavalue of the raster
 with ST_SetBandNoDataValue(rast, null).

 Option 1 and 2 should be controled by exclude_nodata_value and this is the
 only thing that exclude_nodata_value should control.

 Is this the current behavior?
