This is hard to believe. If you're running out of network buffers,
slowing down the data-consuming process ought to make things worse not
better. pg_dump doesn't have any direct way of throttling the backend's
output; that happens when the network queue is full and the kernel
starts blocking the backend's send() requests. I would have taken your
problem to suggest that Windows 2003 doesn't cope very well with a full
network queue.
