Rather than a behaviour change, it is a bug that we are fixing. User
already expects to see copy status printed, so as per user there would be
no behaviour change.

So the idea is to fix it in two places independently. Whatever fix we are
doing for COPY FROM , we would not revert or change that fix when we fix
the COPY TO issue. The base changes will go in COPY FROM fix, and then we
will be extending (not rewriting) the fix for COPY TO after fixing the
\COPY-TO issue.

Also, we already have a fix ready for COPY FROM, so I thought we better
commit this first.
