pst.setNull(2, Types.BLOB) - Mailing list pgsql-jdbc

Hello.

I have just tried to upgrade my jdbc driver, but have a problem with
setNull for blobs. I am using postgresql-8.0-310.jdbc3.jar with
commons-dbcp-1.2.1.jar and postgresql-8.0.1.

The test table:
create table blobtest (a int primary key, b bytea);

Sql to reproduce the problem:
             Connection conn = ...
             PreparedStatement st = conn.prepareStatement("insert into
blobtest (a,b) values (?,?)");
             st.setInt(1, 5);
             st.setNull(2, Types.BLOB);
             st.execute();
             conn.commit();

Stacktrace:
org.postgresql.util.PSQLException: Unknown Types value.

Looks like AbstractJdbc2Statement are handling BINARY,VARBINARY and
LONGVARBINARY, but not BLOB. Is this a bug or should I not use
Types.BLOB?
