1911	[raster] ST_BandSurface returning a multipolygon of a band	dustymugs	dustymugs	"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_???"	enhancement	closed	medium	PostGIS 2.1.0	raster	trunk	fixed	history
