FDW's join pushing down is one of the valuable use-cases of this interface,
but not all. As you might know, my motivation is to implement GPU acceleration

I'm curious how this relates to the pluggable storage idea discussed here https://wiki.postgresql.org/wiki/PgCon_2013_Developer_Meeting and here
I haven't seen a specific proposal about how much functionality should be encapsulated by a pluggable storage system. But I wonder if that would be the best place for specialized table-scan code to end up?
