Yes, if you installed it as such. If you use the MSI installer, this is
the default. If you installed from source, you have to register it
You can also build/install it as a Cygwin binary (non-native). I beleive
the cygwin version can also be set to be either a service or not, but I
don't know what the default is there.
You can use task manager to check if there is a "postmaster.exe" process
active, and the Services snapin to check if the service is installed and

Yes. The client communicates using TCP/IP to the server. As long as you

No, that shouldn't be necessary. Just point your connection to
"localhost" (it has to be TCP based, not Unix sockets. Not sure if
cygwin supports unix sockets, but if it does, then I beleive it's the

This indicates you're running:
a) RC5. You should be running release. I suggest you upgrade, or wait a
day or two for 8.0.1.
b) The native (non-cygwin) version.
