Hello, we are running postgresqlserver on s390 zLinux machines. The distribution is RedHat 7 and RedHat 8, so we do not have the many x86 tools available. We always run 2 instances with a replication (streaming) async mode, the replica is in hot_standby and we use it for read-only accesses. About the setup we have the following question: How is an orderly failover accomplished? Our current procedure is. 1. primary stop 2. promote replica to primary 3. create standby.signal on old primary 4. change primary_conninfo on old primary 5. start old primary as new replica Is this processing correct? Are there any other steps that simplify a failover? How can we be sure that all changes have been transferred from the old master to the replica? thanks in advance
