Thread: upgrade 8.3 -> 8.4 (is it safe?)

upgrade 8.3 -> 8.4 (is it safe?)

From

I am using postgres 8.4 with the 8.3 jdbc driver.

I'd like to upgrade to jdbc 8.4 is there any reason to avoid this
upgrade? Where can I find information regarding possible problems (if any)?

thank you

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
