Not being a Windows user, I don't have much to say about the big
question of whether disabling WER is still a good idea or not. But
I will say that in my experience, behavioral differences between
Postgres started manually and Postgres started as a daemon are bad.
So I think going out of our way to make the cases behave differently
on Windows is probably not a good plan.
