#1583: [raster] Optimize ST_Intersection(raster, geometry) with ST_Clip()
-------------------------+--------------------------------------------------
 Reporter:  pracine      |       Owner:  pracine             
     Type:  enhancement  |      Status:  new                 
 Priority:  medium       |   Milestone:  PostGIS Raster 2.0.1
Component:  raster       |     Version:  trunk               
 Keywords:               |  
-------------------------+--------------------------------------------------
 Now that we can ST_Clip() a raster we can optimize the vector space
 ST_Intersection(raster, geometry) so that it vectorize only the required
 extent (the intersection of the geometry extent and the raster extent)
 instead of all the tile.
