Description
When using the RasterField for raster columns in PostGIS that are not fully managed by Django, the raster table could be of a type that is not supported by the GDALRaster. Examples are out-of-db rasters, or rasters that have an unsupported pixeltype (single bit rasters, 2 or 4 bit rasters).
A paragraph about this could be added to the documentation, and some sanity checks could be added to the raster deserialization here:
