I had a quick look a the idea of just getting rid of walsenders as a
specific entity. Making them normal backends wherever possible. But it
starts running into trouble when you're allowing walsenders to stay
alive well into postmaster shutdown when normal backends are
terminated, so there's probably going to be a need for more ongoing
separation than I'd really like to stop walsenders doing things they
can't safely do during shutdown.
