We already do something very similar to what you're donig in
backend/port/wni32/socket.c :: TranslateSocketError().
So I think it's a good idea to do it, yes.

It's fairly trivial to use, really. See for example pg_SSPI_error in
auth.c. But if it only happens rarely, we shouldn't need it. Let's try it
with just an int for now, and we can perhaps detect the specific cases when
it happens often, and deal with those separately.
I can put together one that uses messages if you want me to (since I can
compile it...) though. I assume you consider your current patch safe enough
not to need help buiklding that part before it hits the buildfarm :-P
