COPY requires special protocol level support so this won't work.

In February of last year Michael Adler made a patch to support copy, but
it was rejected because the copy protocol was broken and a bad copy would
completely hose your Connection. With the new V3 protocol in 7.4 it makes
copy errors recoverable so it can be implemented safely. It's on my todo
list to update his patch for the current driver, but I haven't gotten to
it.
