  Hi


   


  
    Thank you all for the helpful tips. Many thanks to Alex Orlov for the test. He works.
  
  
    I made a second version of the patch and took into account all the comments.
  
  
    
      Patch description: When checking a new cluster, the value of the track_commit_timestamp parameter is determined. 
    
    
      If this parameter is set and the Latest checkpoint's oldestCommitTsXid and Latest checkpoint's newestCommitTsXid are set in the old cluster, then pg_comit_ts is copied.
    
    
      
        The files were processed by pgindent.
