I'm upgrading from 1.2.21 to 2.0.4, which in other words means I need to uninstall the node and delete the old Slony directory before installing the new. Setting up a testing environment will be quite a big job though, what's the worst thing that can happen if I decide to update the live system straight away without testing first? Could it interfere with postgresql?
