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. -HTH Regards, -- Devrim Gündüz Open Source Solution Architect, Red Hat Certified Engineer Twitter: @DevrimGunduz , @DevrimGunduzTR
