I found that sending more than 16k of data in a SQL statement caused a
problem. I was using PyGreSQL but narrowed the error down to
"\postgresql-7.1.2\src\interfaces\libpq\fe-misc.c" pqReadData() and
pqFlush(). After some poking around, it looked like recv was setting
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.
This article describes the problem and work around.

I haven't done much C coding in a few years and don't want to break
other code by blindly doing:
#define errno WSAGetLastError
Does anyone that knows this code want to take a crack at it?
Thanks,
Jeff
