Can I stop the server and modify recovery.conf with this param and restart it again without problems?


It should work. (Sorry I never tried this, like stopping in middle of the recovery and restarting with some changes. Sure there will be answer's here if someone has more insight on this scenario) 

Its good to include this parameter in recovery.conf at the recovery start time. 


Just did some testing, two ways found:

1. You can stop the server and add the recovery_target_time in recovery.conf file to current_time + 1 hr, so that recovery completes consistently till to the specified time and open the server for R/W.
2. You can stop the server and rename the recovery.conf to recovery.done and start the server assuming it has reached to consistent state by this way it opens the server from that point for R/W.

hello , I'm restoring a 7 days ago full backup  + wal files. I have to recover more than 6k wal files and I have no time, I would accept to work with a ~ 3 days ago snapshot, can I stop the recovery process and start the server?, if yes, how?

My recovery.conf file only has this line :

restore_command = 'envdir /etc/wal-e.d/env /etc/wal-e.d/wal-e wal-fetch "%f" "%p"'

Thanks in advance.

You can control the recovery process with recovery_target_time parameter.  This parameter helps you to recover wals till to the acceptable time for you from the snapshot.
