Attempting to setup standby cluster in preperation to migrate away from bitnami/postgresql-ha on another cluster. Using same psql version, and have user+passwords setup correctly.

Replication of data seems to occur, disk space looks about the same. But then the starting of the node fails

FileNotFoundError: [Errno 2] No such file or directory: '/home/postgres/pgdata/pgroot/data/postgresql.conf' -> '/home/postgres/pgdata/pgroot/data/postgresql.base.conf'

I think pgpool was interfering and causing my initial troubles, hence the edits and hidden comments

Start by reproducing the standby-cluster startup with postgres-operator:v1.8.2 on Kubernetes and inspect the reported postgresql.conf to postgresql.base.conf failure. Compare the replication and startup sequence with the provided environment details; done means identifying the cause and confirming that the standby node starts successfully.
