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

[Andrei Verovski]

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 at 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
