The easiest way is moving /var/lib/pgsql/data under /xyz directory
(when the db is not running) and create a symlink in the original
location:
chown postgres: /xyz
su - postgres
mv /var/lib/pgsql/data /xyz/10-data
ln -s /xyz/10-data /var/lib/pgsql/data
Then you can use setup script as usual.
Another alternative is creating a copy of the unit file under
/etc/systemd/system, changing $PGDATA inside that file and run the
setup script. This should be documented on the top of the unit file.
Devrim,

Thank you.
