List,
I've done WAL async replication between two Postgre servers in Pirmary and Standby node as a test bed on two Virtual Machines on CentOS 8. Postgres12.
Now I want to do the same WAL replication on a Production Postgres server to a new standby server.
Is there a way to do configurations for WAL async replication on primary server without affecting the customers / applications that depend on this primary DB server?
As it is a production server, any changes we make to configuration files may affect the services right ? or what unseen problems can arise in this use case?
How to minimize the downtime / without service interruptions from the Primary server while doing WAL replication to a Standby server.
Any hints / directions most welcome .. How will geeks do this in this situation?
Yours,
Krishane
