ST_Retile — Return a set of configured tiles from an arbitrarily tiled raster coverage.
SETOF raster ST_Retile(regclass  tab, name  col, geometry  ext, float8  sfx, float8  sfy, int  tw, int  th, text  algo='NearestNeighbor');
Return a set of tiles having the specified scale (sfx,
sfy) and max size (tw,
th) and covering the specified extent
(ext) with data coming from the specified
raster coverage (tab, col).
				
Algorithm options are: 'NearestNeighbor', 'Bilinear', 'Cubic', 'CubicSpline', and 'Lanczos'. Refer to: GDAL Warp resampling methods for more details.
