That's not what I had in mind for postgres_fdw --- rather the idea is to
avoid needing on-the-fly changes in remote-side settings, because those
are so expensive to make.  However, postgres_fdw is fortunate in that
the SQL it expects to execute on the remote side is very constrained.
dblink might need a different solution that would leave room for
user-driven changes of remote-side settings.
