problem with setting boolean value on AbstractJdbc1Statement

Hello,

I get the following error when the JBoss EJB container attempts to set a
BOOLEAN value on the AbstractJdbc1Statement:

Unknown Types value.
        at org.postgresql.jdbc1.AbstractJdbc1Statement.setObject
            (AbstractJdbc1Statement.java:1423)
        at org.postgresql.jdbc1.AbstractJdbc1Statement.setObject
            (AbstractJdbc1Statement.java:1429)
        at org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.setObject
             (WrappedPreparedStatement.java:607)
        at org.jboss.ejb.plugins.cmp.jdbc.JDBCUtil.setParameter
             (JDBCUtil.java:292)
        .
        .
        .

I'm running Postgres 7.3.2 on Red Hat (and Windows) using the latest JDBC3
driver.

Any thoughts, ideas from anyone?

Thanks,
Stuart
