No.
#def'ing them to be read + write under non-win32. As is done today.
It would change (in port.h):
#ifndef WIN32
#define pgpipe(a) pipe(a)
#define piperead(a,b,c) read(a,b,c)
#define pipewrite(a,b,c) write(a,b,c)
#else
extern int pgpipe(int handles[2]);
#define piperead(a,b,c) recv(a,b,c,0)
#define pipewrite(a,b,c) send(a,b,c,0)
#endif
to
#ifndef WIN32
#define pgpipe(a) pipe(a)
#define piperead(a,b,c) read(a,b,c)
#define pipewrite(a,b,c) write(a,b,c)
#else
extern int pgpipe(int handles[2]);
extern int piperead(a,b,c);
extern int pipewrite(a,b,c);
#endif
And then put piperead() and pipewrite() along with pgpipe() in the C
file. (Naturally, arguments with the correct syntax, but you get the
idea)

pgstat.c, inside the main loop.
#ifdef WIN32
if (WSAGetLastError() == WSAECONNRESET) /* EOF on the pipe! (win32
socket based implementation) */
{
pipeEOF = true;
break;
}
#endif
There's where I notived it. That might be the only place, though -
haven't checked further. If it's the only case, then it's not such a big
deal.
But it might come back to bite us in the future - since it currently
does not actually implement "expected behaviour" of a pipe.
