There is no standard JDBC way I know of, short of reconnecting.
AFAIK there's no way at the protocol level to reauthenticate as a
different user on an existing connection. I believe psql's \c command
actually establishes a new connection.
If you originally connected as the database superuser you could use SET
SESSION AUTHORIZATION to get a similar effect; see
