Updating postgresql jdbc driver to make java code work with postgresql 9.

The jdbc driver extension and the example program PostPicSQL do not work with postgresql-8.4-701.jdbc4.jar,
as PGImage fails to return an Image object. The problem is that PGbytea.toBytes does not returns the right thing.
Probably the data format has changed.

Using the latest code from cvs (:pserver:anonymous@cvs.pgfoundry.org:/cvsroot/jdbc) things work again as expected.
