in /var/log/postgresql/ I've a file with 0kb
it is weird
is there a way to recover all dbs without starting the daemon?

What OS and version are you running? Assuming a Debian/Ubuntu flavor for now.

How was Postgres installed?

So there is a pid file present in the data directory, how about in the run directory, /var/run/postgresql?

Is Postgres running? so:

ps ax|grep post

or

pg_ctl status  -D /var/lib/postgresql/9.3/main

If not what happens if you remove the pid and start Postgres manually, not through supervisor?

because I've another one docker with the same configuration and works
fine (same os, same versione of postgresql)

            until yesterday there were no problem
            right now I see this in the /var/log/supervisor's directory:

            2015-10-01 21:40:18 UTC HINT:  The file seems accidentally

        try...
             ls -la /var/lib/postgresql/9.3/main

        The directory . should be owned by the postgres user, and it
        should have 700, 750, or 770 permissions.   all the files in it
        should also be owned by postgres.

        also look and see if postgres logged anything in its own system
        log files (/var/log/postgresql/9.3  or whatever).
