Problem with creating language by JDBC

Hi there,

I was trying to create language by execute() or executeUpdate(). But the
call always fails with message as

problem running SQL query: CREATE TRUSTED PROCEDURAL LANGUAGE 'plpgsql'
  HANDLER plpgsql_call_handler
.An I/O error occured while sending to the backend.

Following is a snippet of the Java code I have, which works with
creating database, executing other queries:

        PreparedStatement stmt = null;
        ResultSet rs = null;
        try {
            stmt = con.prepareStatement(str);
            System.out.println("Running SQL query: " + str +
"..");
            try {
                //stmt.executeUpdate();
                stmt.execute();
            } catch (SQLException sqle) {
                StringBuffer errMsg = new StringBuffer(
                        "  problem running SQL
query: " + str + ".");
                errMsg.append(sqle.getMessage());
                System.err.println(errMsg.toString());
                ret = false;
            }
            con.commit();
            System.out.println("Query is done.");
        } finally {

I'm using postgresql-8.2dev-501.jdbc3.jar and querying against an 8.3.4
server. If I run the query manually on psql command with same
authentication, it will return successfully. I tried with a later JDBC
driver, it has the same problem.

Regards,

M.
