Those landed in 9.2.3, see release notes for that version:
Fix performance problems with autovacuum truncation in busy workloads
(Jan Wieck)
Fix error in vacuum_freeze_table_age implementation (Andres Freund)
There should be no change in usage, unless you were taking some heroic
methods to overcome the problems and can now discontinue them.
