I can only confirm that that method is *not* implemented.
You would have to use setClob(int parameterIndex, Clob x) instead.

But really, *do not* use any of the getClob and setClob methods, because they
use Large Objects in PostgreSQL, and you should avoid Large Objects.

Use setBinaryStream(int parameterIndex, InputStream x) instead, so that
you can use "bytea" in the database.

By the way, there is a specific mailing list for the JDBC driver, where you
may get better answers.
