    8282'''Open question''': How to fetch the information needed to construct the GDALDataset? Pay attention to the fact that '''you are not asking for raster data yet'''. You only need metadata, for constructing the basic GDALDataset object.

     84 Pierre: So just knowing the raster extent, the pixelsize and the pixeltype is not sufficient? You could do this with a quick query SELECT ST_Extent(rast), min(ST_BandPixelSize(rast, band)), min(ST_BandPixelType(rast, band)) assuming all tiles have the same pixelsize and pixeltype.
