No, because our version of 8.3.x is compiled against 1.2.14
and if 8.4 will work with that then I do not have to re-build
and test 8.3.x with a newer version of Slony and then handle
the change control process for upgrading to the new version
of Slony on the 8.3 server. Then replicate to 8.4, followed
by change control to make it the master, followed by another
round of rebuilding 8.4 with Slony 2.x, and more change
control to manage the upgrade to 2.x. If 1.2.14 will work
I avoid a whole lot of testing and change management.
