Hello community. I have an old Postgresql 9.6 and am trying to create streaming replication; So I can test and easily upgrade the server afterward. I did it before with the same server, but it looks like I have never seen these log lines before: LOG: invalid resource manager ID 130 at 1398/A871F88 As I can see in the log files, the replica was successfully initialized, and everything is ok. Example: 2023-08-31 22:57:17.692 CEST  LOG: consistent recovery state reached at 13CD/180E5800 2023-08-31 22:57:17.692 CEST  LOG: invalid resource manager ID 98 at 13CD/180E5800 2023-08-31 22:57:17.692 CEST  LOG: database system is ready to accept read only connections 2023-08-31 22:57:17.795 CEST  LOG: started streaming WAL from primary at 13CD/18000000 on timeline 1 But I’m a little bit afraid that something might go wrong. Is it something important?
