I'm trying to install OpenACS 4 with PostgreSQL on top of Cygwin. I haven't gotten it to work yet; the main problem right now is that the team developing AOLserver 4 have decided not to continue work on a native port for Win32. As of AOLserver 4 beta 2, they were actively removing Windows specific source code. I looked briefly at running the new AOLserver code under Cygwin, but some of the POSIX threading functions that are needed haven't been implemented in Cygwin yet.
I've also had a few problems installing OpenACS 4 itself (using older AOLserver binaries), but I need to do some more debugging to track them down. I know at least some are Windows specific. I'd be happy to trade notes with anyone else attempting a Win32 installation - perhaps we could even compile a more formal installation guide.
