 Priority:  low      |   Milestone:  PostGIS 2.0.0
Component:  raster   |     Version:  trunk

Comment(by pracine):

 I think a general rule should be: As soon as a function CAN produce nodata
 values (this is the case of ST_Intersection(raster, raster),
 ST_Intersection(raster, geometry) and ST_Clip(raster, geometry)) there
 should be a way to specify the selected nodata value in case the input
 raster do not have one defined.

 Otherwise we have to prepend ST_SetBandNodataValue() every time (if we do
 not want strange results in some cases).
