List archive broken

Hello,

I tried to search the mailing list archives but got only:

                              An error occured!

PQconnectPoll() -- connect() failed: Connection refused Is the postmaster running (with -i) at 'db.hub.org' and
acceptingconnections on TCP/IP port 5439? 


This doesn´t speak well about the backend we use ;-)).

Kind regards

        Andreas (hopefully not repeating someone else because I can´t search
                 the archive).
