One problem with this is that it requires your shell script to have
superuser access to your database, since it is directly running a COPY
command. This may or may not matter, depending on setup - for instance,
you might trust local Unix sockets, meaning someone would need access to
the box first. It's probably best to never have a non-interactive
process able to connect with elevated privileges though.
