PG9.5 allows us to add an oid system column to foreign tables, using
ALTER FOREIGN TABLE SET WITH OIDS, but currently, that column reads as
zeroes in postgres_fdw. That seems to me like a bug. So, I'd like to
propose to fix that, by retrieving that column from the remote server
when requested. I'm attaching a proposed patch for that.

Best regards,
Etsuro Fujita
