## 26.2. Recovery Target Settings

By default, recovery will recover to the end of the WAL log. The following parameters can be used to specify an earlier stopping point. At most one of `recovery_target`, `recovery_target_name`, `recovery_target_time`, or `recovery_target_xid` can be used; if more than one of these is specified in the configuration file, the last entry will be used.

`recovery_target``= 'immediate'`

  This parameter specifies that recovery should end as soon as a consistent state is reached, i.e. as early as possible. When restoring from an online backup, this means the point where taking the backup ended.

  Technically, this is a string parameter, but `'immediate'` is currently the only allowed value.

`recovery_target_name` (`string`)

  This parameter specifies the named restore point (created with `pg_create_restore_point()`) to which recovery will proceed.

`recovery_target_time` (`timestamp`)

  This parameter specifies the time stamp up to which recovery will proceed. The precise stopping point is also influenced by recovery_target_inclusive.

`recovery_target_xid` (`string`)

  This parameter specifies the transaction ID up to which recovery will proceed. Keep in mind that while transaction IDs are assigned sequentially at transaction start, transactions can complete in a different numeric order. The transactions that will be recovered are those that committed before (and optionally including) the specified one. The precise stopping point is also influenced by recovery_target_inclusive.

The following options further specify the recovery target, and affect what happens when the target is reached:

`recovery_target_inclusive` (`boolean`)

  Specifies whether to stop just after the specified recovery target (`true`), or just before the recovery target (`false`). Applies when either recovery_target_time or recovery_target_xid is specified. This setting controls whether transactions having exactly the target commit time or ID, respectively, will be included in the recovery. Default is `true`.

`recovery_target_timeline` (`string`)

  Specifies recovering into a particular timeline. The default is to recover along the same timeline that was current when the base backup was taken. Setting this to `latest` recovers to the latest timeline found in the archive, which is useful in a standby server. Other than that you only need to set this parameter in complex re-recovery situations, where you need to return to a state that itself was reached after a point-in-time recovery. See Section 24.3.5 for discussion.

`recovery_target_action` (`enum`)

  Specifies what action the server should take once the recovery target is reached. The default is `pause`, which means recovery will be paused. `promote` means the recovery process will finish and the server will start to accept connections. Finally `shutdown` will stop the server after reaching the recovery target.

  The intended use of the `pause` setting is to allow queries to be executed against the database to check if this recovery target is the most desirable point for recovery. The paused state can be resumed by using `pg_xlog_replay_resume()` (see Table 9.70), which then causes recovery to end. If this recovery target is not the desired stopping point, then shut down the server, change the recovery target settings to a later target and restart to continue recovery.

  The `shutdown` setting is useful to have the instance ready at the exact replay point desired. The instance will still be able to replay more WAL records (and in fact will have to replay WAL records since the last checkpoint next time it is started).

  Note that because `recovery.conf` will not be renamed when `recovery_target_action` is set to `shutdown`, any subsequent start will end with immediate shutdown unless the configuration is changed or the `recovery.conf` file is removed manually.

  This setting has no effect if no recovery target is set. If hot_standby is not enabled, a setting of `pause` will act the same as `shutdown`.
