"pg_ctl -m fast stop" doesn't shut down with active COPY

This is a repost of:

http://archives.postgresql.org/pgsql-general/2009-03/msg00434.php

I didn't get any response, and it appears to be in contradiction to the
docs:

"SIGINT -- The server disallows new connections and sends all existing
server processes SIGTERM, which will cause them to abort their current
transactions and exit promptly."

http://www.postgresql.org/docs/8.3/static/server-shutdown.html

If you have an open COPY and no data is moving, it simply won't
terminate it. You can terminate it with ctrl-C from psql, but not a
SIGINT to the postmaster or a SIGINT or SIGTERM to the backend.
