RE: WIP: WAL prefetch (another approach)

Hi, 

Thank you for developing a great feature. I tested this feature and checked the documentation.
Currently, the documentation for the pg_stat_prefetch_recovery view is included in the description for the pg_stat_subscription view.

https://www.postgresql.org/docs/devel/monitoring-stats.html#MONITORING-PG-STAT-SUBSCRIPTION

It is also not displayed in the list of "28.2. The Statistics Collector".
https://www.postgresql.org/docs/devel/monitoring.html

The attached patch modifies the pg_stat_prefetch_recovery view to appear as a separate view.

Regards,
Noriyoshi Shinoda
