I've just commited some updates to the JDBC driver. What follows is an excerpt 
of what's been done over the last couple of days.

Now, due to not having a working Linux box at home, I've not had chance to test 
everything, but it's in there for you to try out. I'm busy for the rest of the 
week, so email me if you find any problems and I'll look at it later.

I've got loads more to put in there over the next few days.

        - 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?)
            getBlob(int)
            getCharacterStream(int)
            getConcurrency()
            getDate(int,Calendar)
            getFetchDirection()
            getFetchSize()
            getTime(int,Calendar)
            getTimestamp(int,Calendar)
            getType()
          NB: Where int represents the column name, the associated version
              taking a String were already implemented by calling the int
              version.
        - 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:
            cancelRowUpdates()
            deleteRow()
        - Added new error message into errors.properties "postgresql.noupdate"
          This is used by jdbc2.ResultSet when an update method is called and
          the ResultSet is not updateable. A new method notUpdateable() has been
          added to that class to throw this exception, keeping the binary size
          down.
        - Added new error message into errors.properties "postgresql.psqlnotimp"
          This is used instead of unimplemented when it's a feature in the
          backend that is preventing this method from being implemented.
        - Removed getKeysetSize() as its not part of the ResultSet API

        - Applied modified patch from Richard Bullington-McGuire
          <rbulling@microstate.com>. I had to modify it as some of the code
          patched now exists in different classes, and some of it actually
          patched obsolete code.

        - Updated Implementation to include both ANT & JBuilder
        - Updated README to reflect the changes since 7.0
	- Created jdbc.jpr file which allows JBuilder to be used to edit the
          source. JBuilder _CAN_NOT_ be used to compile. You must use ANT for
          that. It's only to allow JBuilders syntax checking to improve the
          drivers source. Refer to Implementation for more details
