For pushing down an UPDATE/DELETE on a foreign join to the remote, I
created a WIP patch on top of the latest version of the DML pushdown
patch. Attached is the WIP patch. I'd like to propose this as part of
(I'd like to discuss this as a separate patch, though):
https://commitfest.postgresql.org/9/453/
The patch doesn't correctly evaluate the values of system columns of
joined relations in RETURNING, other than ctid. I'll fix that ASAP.
