Replication and Recovery
+
+
+
+ Support named restore points
+
+ Named restore points can be created using a new server function,
+ pg_create_restore_point. A new recovery.conf parameter,
+ recovery_target_name, allows recovery to stop at a named restore
+ point.
+
+
+
+
+ Add new recovery.conf parameter, pause_at_recovery_target,
+ which defaults to on
+
+ This is a behavior change from previous releases, which entered normal
+ running upon reaching the recovery target.
+
+
+
+
+ Add pg_is_xlog_replay_paused, pg_xlog_replay_pause, and
+ pg_xlog_replay_resume functions
+
+
+
+
+ Allow standby servers to send information on running
+ transactions back to the master
+
+ When enabled, this prevents most recovery conflicts on the slave,
+ but may cause MVCC bloat on the master.
+
+
+
+
+ Support streaming base backups
+
+ A new client, pg_basebackup, can be used to perform a streaming base
+ backup.
