Debian 9.5 - postgresql cluster 9.4. It's not a fresh installation - it was a perfectly decently running system, until I tried restarting the service
all commands: /etc/init.d/postgresql start and service postgresql start and systemctl start postgresql behave the same: the the prompt hangs for about 10-15 seconds, and then nothing happens - postgres isn't running!
here's the syslog:

So there are absolutely no indicators about what's wrong. Strangely, the system was running without any problems all along - my application just crashed, and I tried restarting postgres - and now it wont start again.
After several hours of searching, I discovered, that strangely, it can be launched manually.
I logged as the postgres-user and used the command:
/usr/lib/postgresql/9.4/bin/postgres -D /var/lib/postgresql/9.4/main -c config_file=/etc/postgresql/9.4/main/postgresql.conf
it just works fine - no errors, no thing. I even tried adding the '-d 3' to get more detailed output ....however there is nothing out of the ordinary. it runs fine - the problem are just the init-scripts. How do I fix this - or at least find out the root of the problem?
