Well, that sucks.  Apparently, your Windows compiler thinks
elog(ERROR, ...) might return.  Apparently
b853eb97182079dcd30b4f52576bd5d6c275ee71 wasn't good enough for your
compiler; I wonder why not.

I don't want to do that, because adding a default: case to the switch
will prevent the compiler from complaining if somebody introduces
another enum value in the future.  Instead, we can just add a dummy
return at the end of the function.  I'll go do that.
