Dear Adrian and Tom, thanks for your attention. I did an upgrade on Friday. I use to do this every week.
Log file informed: 2016-10-15 06:15:20 BRT [995-1] FATAL: data directory "/var/lib/postgresql/9.5/main" has group or world access 2016-10-15 06:15:20 BRT [995-2] DETAIL: Permissions should be u=rwx (0700). The problem with permissions was already indicated to .pgpass So I did a "sudo chmod 0700 main" at /var/lib/postgresql/9.5/ directory and I could connect postgres again! A cannot understand what happened. How an upgrade changes the permissions of files an folders? I work with more two desktops with the same framework (I7, 8 GB, Ubuntu 16.04, PostgreSQL, ...) and it did not happen. Well, but I have my database available now. Thanks.
