     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.1.0
Component:  raster       |     Version:  trunk

-------------------------+--------------------------------------------------
 Since an underlying C function is being written for use by various
 raster/raster spatial relationship functions, the C function might as well
 be exposed.

 This could be done calling

 ST_Union((ST_DumpAsPolygons()).geom)

 or

 ST_Union((ST_PixelAsPolygons()).geom)

 but it may be that the underlying C function might be faster.  No way to
 tell until the function is written.

 {{{
 ST_Surface(raster rast, integer nband DEFAULT 1) -> geometry
 }}}

 Suggestions on the function name?  ST_Surface?  ST_BandSurface? ST_???
