Heroku Deployment Issue

Couldn't create database for {"adapter"=>"postgresql", "database"=>"develeopment_db", "pool"=>5, "timeout"=>5000, "socket"=>"/tmp/.s.PGSQL.5432"}
could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
