Moving postgresql 9.4 data directory in fedora 22

I would like to know how to move the PostgreSQL database directory in a Fedora 22 installation. In Ubuntu, this is very straightforward by using pg_dropcluster and sudo pg_createcluster -d /the/new/location/ 9.4 main, but Fedora does not appear to have anything of the sort.

I copied the directory /var/lib/pgsql/data to a new location and, did the following:

su - postgres
service postgresql stop
export PGDATA="/the/new/location/"
echo $PGDATA # gives the correct /the/new/location/
service postgresql start
psql
show data_directory;

Which still results in the default /var/lib/pgsql/data...

Could someone please either provide a link to a relevant and up-to-date tutorial or explain how to complete the move?

Note: I am aware that this question has been answered for other distributions and older versions of Fedora and Psql, but it seems a lot of the files have been moved about and none of the approaches seem to work for me.

So it turns out that this method is out of date. The correct way to do it is to add this file with nano /etc/systemd/system/postgresql.service:

.include /lib/systemd/system/postgresql.service
[Service]
Environment=PGDATA=/the/new/location/

I believe this also requires a reboot.

Afterwards, one still has to set up SELinux correctly before PostgreSQL can start up.
