Several ways to already do it,
The one i use for now is:
on SQL side:
SELECT ST_Binary(rast) ...
on Python side:
But i guess/hope we could perform the conversion quicker,
and add the reverse one, NumPy ndarray to Raster, too.
And maybe as you already wishlist to improve/enhance Raster
serialization itself, in 3.0,
we could -maybe- imagine something agnostic enough to allow a very
thin conversion overhead.
