The other files have not yet been written, so pg_waldump cannot read them. If you can find out what was the name of the file that it had before the recycling, you can rename (a copy of) the file to that, and then pg_waldump will be able to read it. (You can try brute-forcing the search for the correct file name). If you have an archive_command-generated archive of WALs, or pg_receivewal, those files should all be readable by pg_waldump. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
