[ovirt-users] oVirt Engine 4.2 -> 4.2.1 Upgrade

Hi ! After oVirt Engine 4.2 -> 4.2.1 Upgrade do I need to run these commands as described in this article https://www.ovirt.org/release/4.2.1/ su - postgres -c "scl enable rh-postgresql95 – psql -d engine" postgres=# DROP FUNCTION IF EXISTS uuid_generate_v1(); postgres=# CREATE EXTENSION "uuid-ossp”; BTW, this yelds error: [root@node00 ~]# su - postgres -c "scl enable rh-postgresql95 – psql -d engine" Unable to open /etc/scl/conf/–! node00 is a dedicated PC with CentOS and oVirt Host Engine. Thanks. Andrei
