I set up the logs using the parameters:
log_connections = on
log_disconnections = on
log_duration = on
log_error_verbosity = terse
log_statement = 'all'
log_timezone = 'localtime'

I think it would be enough to get the log in the file
/var/log/postgresql/postgresql-9.4-main.log . If I set the
logging_collector up the log would became
/var/lib/postgresql/9.4/main/pg_log/postgresql-2015-06-18_XXXXX.log .
I don't understand why postgresql logged before my update and now it
doesn't work anymore.
