Hi All,

I have a three node PATRONI cluster with postgres 17.10 version with PGBACKREST, pgnouncer and haproxy. 

We would like to upgrade postgres 18.4 version. 

What are the high level steps with minimal downtime? Though I did some research already, would like to understand how it's been followed.
