UbuntuでPostgreSQLがactice (exited)なのはそれでいいのかな？
$ systemctl status postgresql
● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor pr>

なんだけど認証までは進んでるっぽい
$ psql
psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5433" failed: FATAL: role "zunda" does not exist
$ sudo -u postgres psql
postgres=# create role zunda with createdb login;
したらエラーが変わったよ。サーバは走ってるんだねえ。
$ psql
psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5433" failed: FATAL: database "zunda" does not exist
$ bundle exec rake db:migrate
$ bundle exec rails s
走ったー。やったね!!
