        - Added new error message into errors.properties "postgresql.notsensitive"
          This is used by jdbc2.ResultSet when a method is called that should
          fetch the current value of a row from the database refreshRow() for
          example.
        - These methods no longer throw the not implemented but the new noupdate
          error. This is in preparation for the Updateable ResultSet support
          which will overide these methods by extending the existing class to
          implement that functionality, but needed to show something other than
          notimplemented:
            moveToCurrentRow()
            moveToInsertRow()
            rowDeleted()
            rowInserted()
            all update*() methods, except those that took the column as a String
            as they were already implemented to convert the String to an int.
        - getFetchDirection() and setFetchDirection() now throws
          "postgresql.notimp" as we only support one direction.
          The CursorResultSet will overide this when its implemented.
        - Created a new class under jdbc2 UpdateableResultSet which extends
          ResultSet and overides the relevent update methods.
          This allows us to implement them easily at a later date.
        - In jdbc2.Connection, the following methods are now implemented:
            createStatement(type,concurrency);
            getTypeMap();
            setTypeMap(Map);
        - The JDBC2 type mapping scheme almost complete, just needs SQLInput &
          SQLOutput to be implemented.
        - Removed some Statement methods that somehow appeared in Connection.
        - In jdbc2.Statement()
            getResultSetConcurrency()
            getResultSetType()
            setResultSetConcurrency()
            setResultSetType()
        - Finally removed the old 6.5.x driver.

- These methods in org.postgresql.jdbc2.ResultSet are now implemented:
getBigDecimal(int) ie: without a scale (why did this get missed?)
