Disallow COPY FREEZE on foreign tables. This didn't actually work: the COPY succeeds, but the FREEZE optimization isn't applied. There doesn't seem to be an easy way to support FREEZE on foreign tables, so let's follow the precedent established by commit 5c9a5513a3 by raising an error early. This is arguably a bug fix, but due to the lack of reports, the minimal discussion on the mailing list, and the potential to break existing scripts, I am not back-patching it for now.
