------------------------------------------------+------------------------
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:
