#1519: [raster] ST_MapAlgebraExpr : provide more keyword substitution
  Reporter:  strk         |       Owner:  pracine

  Priority:  medium       |   Milestone:  PostGIS 2.0.0
 Component:  raster       |     Version:  trunk        
Resolution:  fixed        |    Keywords:               
Changes (by strk):

  * status:  new => closed
  * resolution:  => fixed


 So, r8994 implements the idea in previous comment for ST_MapAlgebraExpr.
 Doesn't add the "RAST.v", to avoid an additional keyword substitution pass
 while still maintaining backward compatibility.

 Didn't touch ST_MapAlgebraFnc, which would likely be nice to also get
 those additional params.

 Surely the expression-based version is easier to expand in a backward
 compatible way.

 Beside, the keyword substitution code may probably be faster than it is.
