So what you're saying (and what the buildfarm seems to confirm, since
we are still seeing "Permission denied" failures from time to time,
eg [1]) is that all that code that bed90759f added to deal with
delete-pending is just junk, because we never get that far if the
file is delete-pending.  So shouldn't we remove all of it?  (That's
lines 214-276 in win32stat.c, plus some earlier declarations that
would now be unneeded.)

I'd be kind of inclined to change pgwin32_open() to use
microsoft_native_stat, as well, because these two functions
really ought to be handling this exactly alike.
