[SOLVED] Postgresql and systemd - Unable to start or enable service

I'm trying to run postgresql in a pure systemd machine.

i've done a fresh install of postgresql using pacman as instructed in the wiki. However when i try to start the service i get the following:

user@frodo:~$ sudo systemctl start postgresql.service
Failed to issue method call: Unit postgresql.service failed to load: No such file or directory. See system logs and 'systemctl status postgresql.service' for details.

user@frodo:~$ sudo systemctl status postgresql.service
postgresql.service
          Loaded: error (Reason: No such file or directory)
          Active: inactive (dead)

So it seems the package has no systemd service files included. Did anyone got around to make one of these?

Re: [SOLVED] Postgresql and systemd - Unable to start or enable service

The PostgreSQL package on [testing] has a service file for systemd.

Re: [SOLVED] Postgresql and systemd - Unable to start or enable service

Thanks. I've reinstalled the package from testing.

However i'm still unable to start the postgresql server. this time it goes like this:

user@frodo:~$ sudo systemctl start postgresql.service
Job failed. See system journal and 'systemctl status' for details.

user@frodo:~$ systemctl status postgresql.service

Uncomment PGROOT in /etc/conf.d/postgresql.

Re: [SOLVED] Postgresql and systemd - Unable to start or enable service

well, i've managed to fix the problem.

it seems that the wiki is missing a couple of steps. so i manually done the following:

i) create the data directory (acordingly  with the PGROOT variable set before in the config file)

user@frodo:~$ sudo mkdir /var/lib/postgres/data

ii) set /var/lib/postgres/data ownership to user 'postgres'


iii) As user 'postgres' start the database.

user@frodo:~$ sudo -i -u postgres
[postgres@frodo ~]$ initdb  -D '/var/lib/postgres/data'

iv) start the service as root

user@frodo:~$ sudo systemctl start postgresql.service

that should be it.

Issuing a systemctl status should return

user@frodo:~$ sudo sudo systemctl status postgresql.service
postgresql.service - PostgreSQL database server
