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
shouldavoid 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.

Yours,
