Unable to start postgresql.service?
OP seems to be using RHEL7 or CentOS7, as indicated by the systemctl commands. If so, the service . restart commands won’t work.
Finally, I figured this one out. There was already a file present
/usr/lib/systemd/system/postgresql-9.6.service So, may be due to the presence of this file, I was not able to start postgresql.service. Then I tried to start postgresql-9.6.service as follows:
[code_master5@BitBox ~]$ sudo systemctl start postgresql-9.6.service Failed to start postgresql-9.6.service: Unit postgresql-9.6.service not found. And, as you can see the output, again it failed.
I simply deleted the file using sudo as I thought may be postgresql.service file is not being created by relevant program due to the presence of this file. Then I restarted the system. It’s working fine since then, as you can see the output below:
[code_master5@BitBox ~]$ sudo systemctl status postgresql.service [sudo] password for code_master5: ● postgresql.service - PostgreSQL database server Loaded: loaded (/usr/lib/systemd/system/postgresql.service; enabled; vendor p Active: active (running) since Sat 2017-01-28 09:31:30 IST; 7h ago Main PID: 342 (postgres) Tasks: 6 (limit: 4915) CGroup: /system.slice/postgresql.service ├─342 /usr/bin/postgres -D /var/lib/postgres/data ├─358 postgres: checkpointer process ├─359 postgres: writer process ├─360 postgres: wal writer process ├─361 postgres: autovacuum launcher process └─362 postgres: stats collector process Jan 28 09:31:26 BitBox systemd[1]: Starting PostgreSQL database server.

I would surely like to warn all those having same problem. Please do whatever I did at your own risk. Since these are system files. Messing with these can spoil your weekend!
I am still a bit confused on this though. Explanations are welcome!
postgres запускается, но не запускается

Что тебе нужно подробнее? здесь и так все ясно написано
ну, видимо, мне не ясно, раз я спрашиваю. Логично же.
# psql psql: could not connect to server: Connection refused Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? я не понимаю, что ему нужно от меня?
postgresql.service — запускает все настроенные инстансы постгреса в убунте, для того чтобы запустить нужный нужно стартовать postgresql-.service.

createuser —interactive сделай, добавь пользователя дай ему нужную роль, зайди от него.
В соединении отказано, всё работает, просто у тебя нет доступа
ну, видимо, мне не ясно, раз я спрашиваю. Логично же.
Ну, кроме вчитаться в текст я тебе больше ничего предложить не могу

Это не значит, что нет доступа, это значит, что там попросту некому это соединение принимать.
вот жесть-то, и советчики такие же.
Ты бы внимательно прочитал на что отвечаешь.
Там не то, что ролей, там и самого процесса постгресса нет
# psql psql: could not connect to server: Connection refused Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? Тьфу блин, ай нуу, пойду кофе пить и просыпаться 😀
Значит есть /var/lib/postgresql/версия/pg_log/*.log
Покажи systemctl list-units|grep postgres
Там должен быть сервис вида postgresql@9.5-main.service. Вот его и запускаешь, systemctl start postgresql@9.5-main.service.
Если нет, то смотришь в /var/lib/postgres, есть ли там что-нибудь. Если там пусто, значит у тебя нет базы, и ее нужно создать.
Точно нет? Показывай /etc/init.d/postgresql — посмотрим, что там в убунтушном инит-скрипте накручено.
Какой инит-скрипт, у него systemd.
