If they are just test environments, why a whole dedicated cluster per instance? Just give each a unique name for the database and run it all on one cluster.
I'd also go back and reconsider why these are separate machines in the first place and make sure you're not violating any assumptions that were made.
I am trying to consolidate some machines in my server room particularly in the testing environment and I was hoping someone could point me in the right direction.
I currently have three machines running PostgreSQL for testing purposes. Each week a backup is made of the production database and this is deployed onto these three machines. None of these machines is any where near capacity. I would like to host all three instances on one machine.
I know that "initdb" can be used to create additional installations, but the part I am unsure about is the tablespace. The production database has a tablespace defined that resides on its SSD. When I use the production backup, I have to create a mount point on the test machine with the same name as the one on the production database. I am not certain how I would handle this situation if I am serving three separate instances of that database from one computer.
