Hi,
I have in my company 3 postgresql nodes(v9.6) that are configured as one
primary and 2 slaves. The repmgr tool is reponsible for the replication. I
want to upgrade all the nodes to version 10.4. I know that PostgreSQL
doesnt support streaming replication between different major versions. Did
someone try this kind of upgrade without having any downtime ?
Thanks , Mariel.
