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();
