Would COPY issued through JDBC actually work?  My understanding is that for
non-postgres uid clients the COPY command is restricted to using stdin/stdout
only.  Or perhaps it's an artificial limitation imposed by psql.  I don't think
I've seen a COPY TABLE JDBC extension in the documentation.

Resetting System.cin/System.cout to a file, then issuing a COPY TABLE might
be worth investigating, but that's a hack.
