Postgresql 9.2 Ubuntu - is not starting

Hi guys,

I've installed potgres on a Ubuntu machine.

When I start it, it doesn't start...

> /etc/init.d/postgresql status

*●* postgresql.service - PostgreSQL RDBMS
> Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor
> preset: enabled)
> Active: *active (exited)* since Tue 2016-08-02 19:54:06 UTC; 7min ago
> Process: 12963 ExecStart=/bin/true (code=exited, status=0/SUCCESS)
> Main PID: 12963 (code=exited, status=0/SUCCESS)
> Tasks: 0
> Memory: 0B
> CPU: 0
> CGroup: /system.slice/postgresql.service

But when looking for the process:
ps fax/ps aux

... it doesn't show postgres.

Also, the logs aren't being created. the pg_log folder is empty.

It's my first time using Ubuntu....

I've done a pg_basebackup from my master and I'm trying to start this slave
server.

Do you guys know what should be going on?

Cheers
Patrick
