Was that a backend that you directly killed? Or the postmaster? The subsequent connection failures suggest it was the postmaster. Killing the postmaster is not a supported operation, not on Windows and not anywhere else either. It's in the category of "doctor, it hurts when I do this".
The headshot was done on random backends. Perhaps in some of those tests the postmaster was taken down though :) I didn't check postmaster.pid all the time.
