How about getting a simple backtrace from a couple of the stuck postgres
processes? And from the postmaster which should be accepting new
connections... Or does that also hang completely?
How to get one? Well, since we don't have the MSVC build yet (yeah,
yeah, eventually), you can only get a semi-backtrace that only looks at
exported symbols. You can get this using process explorer (thread tab,
click stack), using WinDBG or using Visual Studio (you'll need VS 2005,
and you need to check the option for "Load DLL exports" in
options->debugging->native).
Oh, btw, if there is a 3rd firewall on the box the standard
recommendation of uninstalling it definitely sounds like a good plan :-)
