[ovirt-users] 4.2 upgrade question

[KSNull Zero]

Hello!
Currently we run 4.1.9 and try to upgrade to the latest 4.2 release.
Our DB server is on separate machine and run PostgreSQL 9.2.23.

During upgrade the following error occurs:
[WARNING] This release requires PostgreSQL server 9.5.9 but the engine
database is currently hosted on PostgreSQL server 9.2.23
[ ERROR ] Please upgrade the PostgreSQL instance that serves the engine
database to 9.5.9 and retry.

Ok, so we need to upgrade PostgreSQL.
The question is - do we need to have exact 9.5.9 version of PostgreSQL ?
Because if we upgrade PostgreSQL to the latest available 9.5.12 the same
error occurs saying that client and server version mismatched and upgrade
terminates.
Thank you.
