Ihave prepared an initial patch for COPY command progress reporting.

Could you tell me why these columns are necessary in *progress* view?
If we want to see what copy command is actually running, we can see
pg_stat_activity, instead. For example,
SELECT pc.*, a.query FROM pg_stat_progress_copy pc, pg_stat_activity a WHERE pc.pid = a.pid;

Thanks for the patch!
With the patch, pg_stat_progress_copy seems to report the progress of
the processing on file_fdw. Is this intentional?
