Yeah, this is a known problem on Windows: it provides a stat() function
that fails on large files.  There's been some discussion of how we might
work around that, most recently here:
https://www.postgresql.org/message-id/flat/1803D792815FC24D871C00D17AE95905CF5099%40g01jpexmbkw24

but that hasn't been turned into a patch and you shouldn't
hold your breath waiting for it to happen :-(.  There's probably
no chance that the eventual fix would be safe to back-patch into
existing release branches, either.

So ... we might have a fix for this someday, but probably not soon.

It is annoying that we're just reporting "Unknown error" though.
That could be improved to show something more specific without
a lot of work, I imagine.
