I didn't have any problems with that, but I sure had problems when I
failed to upgrade my JDBC driver to the 9.0 version when we upgraded
the backend to 9.0.  Unless you have a very specific reason to do
otherwise, I suggest that you follow the advice here:

http://jdbc.postgresql.org/download.html#current
