As far as Pgpool-II concerns, that's generally true. I don't know what
version of Pgpool-II you are using, and trying to migrate to but if
you are using Pgpool-II dedicated extensions, be sure to upgrade them
as well. For more information regarding Pgpool-II version up, please
refer to the release notes sections.
