restore_command = 'cp /backup/postgresql/wal/%f %p'
recovery_target_time = '2023-07-09 17:36:08'
recovery_target_inclusive = true

- create recovery.signal file
touch recovery.signal

- start PostgreSQL server with the data in the temporary directory
pg_ctl start -D /backup/postgresql/tmp -l /tmp/reco.log


- check logfile; at the end of the recovery you will be asked to execute the following fonction in order to open the instance
