PQputCopyData/PQputCopyEnd are only concerned with transferring data.
After you're done with that, you should call PQgetResult to find out the
COPY command's completion status.  You should get PGRES_COMMAND_OK,
otherwise it'll be an error result.

Um ... you could have read the manual:
http://www.postgresql.org/docs/9.3/static/libpq-copy.html
Or looked at the source code for psql, which as you noted has no problem
displaying errors for COPY.
