Here is the requested details regarding the psql.exe problem. There is
difference in how non-blocking socket connects (i.e. using fcntl to
set O_NONBLOCK) are handled in 1.1.4 and 1.1.5-3. Specifically, in
1.1.4 connect returns 0, while in 1.1.5-3 connect returns -1 with errno
set to EAGAIN (i.e. No more processes). BTW, by reading the Solaris
man page for connect, 1.1.4 may not have got it quite right either.
connect should return -1 with errno set to EINPROGRESS for non-blocking
connects that cannot be established immediately.

Attached is code to duplicate the problem. Try running the client on a
1.1.5-3 machine, the server can run on any machine:

$ server -p 13131&
$ client -h <YourServerHostName> -p 13131
