I have a simple web page in Ruby On Rails with postgresql database, but when I run sever I have this error, I don't Know that I do. I use postgresql because heroku need that the aplication is in postgresql.
I work in ubuntu 13.10
The error is:
PG::ConnectionBad could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I need help
thanks

“Could not connect to server: Connection refused” To be sure that PostgreSQL is running, you can also restart it with systemctl restart postgresql. If this does not fix the problem, the most likely cause of this error is that PostgreSQL is not configured to allow TCP/IP connections.
The PostgreSQL database service is available on localhost and the default PostgreSQL port is 5432 . A default user ( hosting-db ) and database ( postgres ) exist so you can quickly test your connection and perform management tasks.
If you are trying to connect to a Postgres instance on the same host as your terminal, you can run lsof -p :5432 which will show which, if any, processes are listening on that port. The postgres process should be connected there. You can also look at the listen_address and port value in your postgresql.
Open Windows Firewall Port As an alternative you can go to Control Panel -> Systems and Security -> Windows Firewall -> Allow a program or feature through Windows Firewall -> Advanced Settings -> New Rule: Rule Type: Port. TCP or UDP: TCP. Specific local ports: 5432.
Just create a softlink like this,this works for me
$ sudo ln -s /tmp/.s.PGSQL.5432 /var/run/postgresql/.s.PGSQL.5432

Also you are able to force stop and then force start the server
sudo service postgresql stop --force
sudo service postgresql start --force
