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.
It really is that simple. On Linux, at least, it takes me less than two minutes to:
1. Pause streaming replication between 2 nodes.
2. Stop PG on both nodes.
3. Install the new software.
4. Start PG on both nodes.
5. Resume streaming replication.
That's using PowerShell to do everything; a noticeable part of that 110 seconds is the ssh overhead of logging in and out of servers over our network, and even more is taken up by me scanning for errors between each step, and then pasting the next set of commands.
If all your database servers are Windows, then the PS to stop, install and start on a remote node should be even faster (especially if you don't have replication).
