Hi, Thanks for the great new feature.
Applied patches include adding wait events LogicalParallelApplyMain, LogicalParallelApplyStateChange.
However, it seems that monitoring.sgml only contains descriptions for pg_locks. The attached patch adds relevant wait event information.
Please update if you have a better description.
Noriyoshi Shinoda
