Hi, Thanks all for your replies and help! I already thought that it’ll be possible to just install binaries in different locations. My current installation I have all done using one binary location and initdb.. not a very good solution on hindsight.. Oh, and I’m on RHEL 7. I used the installation packages from EDB for Postgres. Previously I did do a minor upgrade - shutdown all clusters and upgrade, then startup all.. but now they start doing difficult with downtime for all applications at the same time, so with next upgrade, I’ll separate all binaries.
