Re: Multiple clusters with same tablespace location
Thanks for the response Melvin.
The issue is that both clusters are using a base_backup and wal restore from the same master database, so when they are restored, the tablespace will already exist. Is there a way to change the tablespace location during the recovery process?

You run the risk of overwriting a file with the same name from a different cluster.There is no reason why you cannot have separate directories for each cluster/tablespace, so why ask for trouble?
