Does the SCM just terminate the process, or does it at some point give
us an error code?

In theory, yes. However, it only affects USER handles, which is
basically windows, buttons etc. So what it basically means is that a
hacked PostgreSQL process can be used to send messages, for example, to
other windows running in the same session. Which only affects things if
pg is started from the commandline, and not as a service.
I don't think it's enough that we need to care about it really. I'm
thinking we could perhaps even just never set that, and not bother with
the version check...
But perhaps we should set it only when launching as a service, and not
when running from the commandline?
