After applying the latest published PostgreSQL security patches, we experienced issues on our replicas. We first updated two of our replica servers running pg14 and pg15. The replica services were running during the binary update. After the binary update was completed, we restarted the relevant replica services. Upon observation, we noticed that the replicas were waiting at the last checkpointed redo file during the startup phase. Meanwhile, although we performed the same operation on our other servers, we did not encounter such an issue on those. Has anyone else encountered a similar problem?
1. What specific minor version numbers?
2. Did you shut down PG before applying the patches?
