The immediate cause of the WAL retension is the archive failure. PostgreSQL, while archiving is enabled, won't remove a WAL file until it is successfully archived. You will see the lines like the following in sergver log if archive failure happened. > 2022-03-03 17:15:21.314 JST LOG: archive command failed with exit code 1 If the archive command emitted some error messages, it can be caught in the server log together. The follwoing error is emitted by the archive_command "cp %p /archive/%f". > cp: cannot create regular file '/archive/000000010000000000000001': No such > file or directory regards. -- Kyotaro Horiguchi NTT Open Source Software Center
