I have added this thread to TODO.detail/libpq.

> I found that sending more than 16k of data in a SQL statement caused a

> "\postgresql-7.1.2\src\interfaces\libpq\fe-misc.c" pqReadData() and

> errno to ENOENT for some reason.  I figured out why today.  Win32
> sockets don't set errno at all.  ENOENT was just left in errno from
> some earlier call.

> #define errno WSAGetLastError
