Yes. That's what PITR is about. Read the manual for details.
If you look at the recovery.conf.sample you'll find a variable
recovery_target_time that must be set. Unless I missed something this
isn't explicitly stated in the docs but the comment in the sample conf
is pretty clear.
Alternatively you can define a transaction id (recovery_target_xid).
Of course you must have a backup created before the incident and all WALs
up to the time of the incident.
