Why do you think you cannot do that?
In the long run, you'll be sorry if you don't.
It is just a matter of replacing the software and restarting the database server.

There is nothing fundamentally evil about upgrading the client.

But what is the point? Why are you worried about client bugs more than
about server bugs? The latter are much more likely to eat your data.

But then, if you are using Windows, perhaps you don't care a lot about
your data...
