Hi,

I see a performance issue on win32. This problem is causes by the
following URL.

On win32, default SO_SNDBUF value is 8192 bytes. And libpq's buffer is
8192 too.

pqcomm.c:117
#define PQ_BUFFER_SIZE 8192

send() may take as long as 200ms. So, I think we should increase
SO_SNDBUF to more than 8192. I attache the patch.

Regards,
