BUG #5637: JDBC driver method setClob always uses getAsciiStream()

The following bug has been logged online:

Bug reference:      5637

PostgreSQL version: 8.4
Operating system:   Windows XP SP3
Description:        JDBC driver method setClob always uses getAsciiStream()
Details:

Using driver: postgresql-8.4-701.jdbc3.jar

The method setClob() in the AbstractJdbc2Statement calls the method
getAsciiStream() on the provided Clob.
This leads to problems if the given Clob contains an UTF-8 encoded string.

Should the driver call getCharacterStream() instead? Can this problem be
solved in a different way?

Relevant code from the class:

    public void setClob(int i, Clob x) throws SQLException
    {
        checkClosed();

        if (x == null)
        {
            setNull(i, Types.CLOB);
            return;
        }

        InputStream l_inStream = x.getAsciiStream();
        ...
