Hello!

Running Ubuntu 13.04 since it's release.
Suddenly I am having problem with Postgres, googled and tried out some suggestions for getting postgres right again - but failing :
Setting up postgresql-common (140) ...
* Starting PostgreSQL 9.1 database server * The PostgreSQL server failed to start. Please check the log output:
2013-06-18 10:08:58 CEST LOG: could not bind IPv4 socket: Cannot assign requested address
2013-06-18 10:08:58 CEST HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
2013-06-18 10:08:58 CEST WARNING: could not create listen socket for "172.16.34.24"
2013-06-18 10:08:58 CEST FATAL: could not create any TCP/IP sockets

When trying to upgrade, this error destroys my day:
I run the command -> sudo apt-get upgrade
but, nothing happens - due to above failure.

Why is this problem occuring now and what can I do to fix it / bypass it ?
