Here is my short note about installing PostgreSQL 9.3.1 on Fedora 19.

Add Postgresql yum repository to Fedora 19 (x64):
(see http://yum.postgresql.org/repopackages.php for up to date list of repositories)

$ wget http://yum.postgresql.org/9.3/fedora/fedora-19-x86_64/pgdg-fedora93-9.3-1.noarch.rpm
$ sudo rpm -i pgdg-fedora93-9.3-1.noarch.rpm
$ sudo yum update

Install PostgreSQL 9.3:

$ sudo yum install postgresql93
$ sudo yum install postgresql93-docs
$ sudo yum install postgresql93-server
$ sudo yum install postgresql93-contrib
$ sudo yum install postgresql93-devel
$ sudo yum install pgadmin3_93 pgadmin3_93-docs

Which Slovenian locale do I have installed on my system?

$ locale -a | grep sl_SI
sl_SI
sl_SI.iso88592
sl_SI.utf8

Initialize cluster with PGDATA on mount point of my choice:

// enter as a single line!!
$ sudo su - postgres -c '/usr/pgsql-9.3/bin/initdb 
   --locale=sl_SI.UTF8' --pgdata=/u01/app/pg93/data


The files belonging to this database system will be owned 
by user "postgres".This user must also own the server process.

The database cluster will be initialized with locale "sl_SI.UTF8".
The default database encoding has accordingly been set to "UTF8".
initdb: could not find suitable text search configuration for 
locale "sl_SI.UTF8" 
The default text search configuration will be set to "simple".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A,
 or --auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

  /usr/pgsql-9.3/bin/postgres -D /u01/app/pg93/data
or
  /usr/pgsql-9.3/bin/pg_ctl -D /u01/app/pg93/data -l logfile start

Change ip/port on which postgres listens

$ sudo nano /u01/app/pg93/data/postgresql.conf
I uncommented:
listen_addresses = 'localhost'
port = 5432

Start PostgreSQL

$ sudo systemctl start postgresql-9.3.service

Optionally enable PostgreSQL autostart on boot

$ sudo systemctl enable postresql-9.3.service

Now, you can also create shortcut to PG Admin that will point to /usr/pgsql-9.3/bin/pgadmin3.
