I don't think there's any support for forcing these params at the moment.

You could modify the JDBC driver to hard-code these parameters and just
use your hacked JDBC driver. That'd probably be a maintenance mess in
the long run, though. It'd be better to write a patch to add JDBC URL
parameter support for overriding them, start using a patched driver you
recompile yourself, and submit that to pgsql-jdbc(at)postgresql(dot)org for
inclusion in future versions so you don't have to worry about keeping it
up to date.
