That seems to be leaving aside the fact that we don't currently have any
notion of how to allow FDWs to write the foreign tables.

What is more, isn't the postgres FDW about talking to any postgres
source? If so, does it have special smarts for when we are talking to
ourselves? And if it doesn't then it seems unlikely to be an acceptable
substitute for allowing talking direct to a sibling database.

I'm not at all yet sold on Simon's plan, but I'm skeptical that an FDW
would adequately meet the case if we wanted to go that way.
