#1520: [raster] ST_MapAlgebraExpr : do not convert expression to uppercase

 Reporter:  strk    |       Owner:  pracine      
     Type:  defect  |      Status:  new          
 Priority:  medium  |   Milestone:  PostGIS 2.0.0
Component:  raster  |     Version:  trunk        
 Keywords:          |  
--------------------+-------------------------------------------------------

Comment(by strk):

 Since things are moving, could we also protect the keywords a bit more ?
 So that it is less likely that your expression wants to use the "rast"
 substring in the name of a function or a table or a column ?

 Also, since I added "rast.x" and "rast.y", could the current "rast" also
 become "rast.val"
 and unify the set of keywords in both 1-raster and 2-raster versions ?
 Like for 2-rasters could be "rast.x", "rast.y", "rast.val1", "rast.val2"
