Hmm, are you sure about that?  I get

ERROR:  column "foo" of relation "foo" does not exist
LINE 2:   on conflict (id) do update set foo.id = 1;
                                         ^

in every branch back to 9.5 where ON CONFLICT was introduced.

I'm checking branch tip in each case, so conceivably this is
something that was changed post-11.0, but I kinda doubt we
would have back-patched it.
