> Sometimes it is needed to postprocess schemas after they are fetched from the external sources. Some examples of postprocessing:
>  * make sure all the defaults are set correctly, and update schema if not.
>  * insert marker columns into records with no fields (no writable as parquest)
>  * ...
> Would be great to have a way to plug in custom post processors.
