After more research, I realize that both of the above patches are wrong.
Sorry for the gyrations but I went into frenzy mode due to the impending
1.1.5 release (which if I remember correctly was suppose to be
yesterday)...  I was also thrown off by Cygwin's strerror(EAGAIN)
returning "No more processes" instead of "Resource temporarily
unavailable" as on other UNIXes (at least Solaris and RedHat 6.2 Linux).

Anyway, I now think that PostgreSQL's psql should be changed to deal
with the possibility of errno equal to EAGAIN when connect() returns -1.
See attached patch for details.

Does anyone else concur?


P.S. From reading the MSDN, it appears that Win32 psql should be checking
