Fix PostgreSQL
After installing a patch for CentOS (as simple as running yum update), when there is a fix for PostgreSQL, the PostgreSQL service script needs to be changed back to using the custom data directory.
* Edit /etc/systemd/system/multi-user.target.wants/postgresql-9.4.service
Replace
Environment=PGDATA=/var/lib/pgsql/9.4/data/
with
Environment=PGDATA=/opt/pgsql/9.4/data/
- Run
systemctl daemon-reload
- Run
systemctl restart postgresql-9.4.service
