I think that the bottom line is that {like any DBMS system} effort is needed to make PostgreSQL run smoothly on any platform, but for Windows support is still fairly new, while on POSIX systems all the kinks have had plenty of time to get worked out. So it should not be unexpected that there will be more problems seen on Windows platforms than on POSIX type platforms. Even so, I think that the progress on Windows has been excellent and that PostgreSQL is definitely a viable alternative to traditional commercial systems. In all cases (Windows or other alternatives) we should use thoroughly tested and carefully configured systems to store our business data. Nothing new or remarkable here. Just common sense.
