Hello ,
 I do a full-backup of ovirt-engine,instaled ovirt-engine in new host , drop database postgres and create a new with this steps:

 1-drop database postgres;
 2- create database template1 with owner=postgres encoding='UTF-8' 
   lc_collate='en_US.utf8' lc_ctype='en_US.utf8' template template0;
 
and after this steps I restores backup of ovirt-engine and run engine-setup, upgrade works now.

With this steps I can obtain somethings erros in the future?

Thanks,

Marcelo Leandro

Thank you for reply, 


"BZ 1515635 [RFE] Drop uuid_generate_v1() internal implementation and use the implementation from standard PostgreSQL uuid-ossp extension
We have added a requirement for uuid-ossp PostgreSQL extension to be present in engine database. For databases managed by engine-setup this is performed automatically, but non-managed databases (usually remote databases) this needs to be done manually by administrators. "


my database is  managed by engine-setup, so i think that is perfomed automatically. I know that problem in my database , but I instaled it`s whith engine-setup com default options.

I try an new instalation in new host and restore backup and when I try update I had take the same error.


Very thanks!!

You need postgresql 9.5, following the information here should give you
everything you need:

https://www.ovirt.org/release/4.2.1/

Also look at the information below 'What's New in 4.2.1' it has some
information on upgrading the uuid generation which requires some manual steps.
