#2030: [raster] n-raster ST_MapAlgebra
 Reporter:  dustymugs    |       Owner:  dustymugs    
     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.1.0
Component:  raster       |     Version:  trunk        
 Keywords:               |  
 This is to replace ALL ST_MapAlgebra functions, 1 and 2 raster variants.
 The question I need to address is whether or not passing a single raster
 multiple times to the C side is efficient (multiple points to the same
 memory address).  If the answer is yes, the supporting multiple bands from
 one raster is easy...
