#1557: ST_MapAlgebraExpr advertising X and Y as float8 types

 Reporter:  strk    |       Owner:  pracine      
     Type:  defect  |      Status:  new          
 Priority:  medium  |   Milestone:  PostGIS 2.0.0
Component:  raster  |     Version:  trunk        
 Keywords:          |  
--------------------+-------------------------------------------------------
 The prepared statement implementation is pretending that all substituted
 keywords are float8 types. This in turns break some usages. My expression
 that used to work is broken, in particular.

 X and Y are integer, will always be integers. Advertising as such should
 help. We know what goes were, so we can as well hard-code integers for
 X/Y.
