Hello, We are seeing a strange issue with postgresql streaming application in sync mode.
We are using postgresql 9.6. Old version because of some specific requirements. We have setup cluster with master-standby using pacemaker. When we kill master using killall -9 postgres. The failed primary has few records extra than standby node. We have done setup with synchronous_commit = remote_apply and have set synchronous_standby_names=server_name. As the failed primary is having more data, How is it possible that primary is committing transaction before they were applied on standby with synchronous_commit=remote_apply? Please share if you have any thoughts. Are we missing any config ? Thanks !
