How to raise extra a Postgres-ha replica of the cluster for further work outside the cluster?

Question

PostgreSQL

Hello. Postgres-Ha from bitnami (1x R/W and 1x synchronous Standby)

hangs on the local k8s cluster , everything is fine, only we need to temporarily move from this hardware for maintenance. Since the system is working at full capacity, I want to try to avoid a drop in service. To do this, I thought to raise the database on another hardware, one server is enough, without lotions. Set it up as a replica, and at the right time switch services to a new database and, accordingly, turn on the database itself as R / W. I did not come up with a smarter scheme. But even with this scheme, questions arise, because I don’t quite understand how and where I should configure the replica, because pgpool and repmgr work in Postgres-Ha from bitnami ... Well, despite all this, I'm from the database to you.







Thanks in advance for your advice!
