Below are my review comments for the v3 patch. ======
1. Commit message (An earlier review comment [Peter-v2] #2 was only partly fixed) "there are no longer any relation information" --> "there is no longer any relation information" ~~~ 2. doc/src/sgml/monitoring.sgml + <entry><structname>pg_stat_subscription_activity</structname><indexterm><primary>pg_stat_subscription_activity</primary></indexterm></entry> + <entry>One row per subscription, showing statistics about subscription + activity. + See <link linkend="monitoring-pg-stat-subscription-activity"> + <structname>pg_stat_subscription_activity</structname></link> for details. </entry> </row> Currently these stats are only about errors. These are not really statistics about "activity" though. Probably it is better just to avoid that word altogether? SUGGESTIONS e.g.1. "One row per subscription, showing statistics about subscription activity." --> "One row per subscription, showing statistics about errors." e.g.2. "One row per subscription, showing statistics about subscription activity." --> "One row per subscription, showing statistics about that subscription." ----- [Peter-v2] https://www.postgresql.org/message-id/CAHut%2BPv%3DVmXtHmPKp4fg8VDF%2BTQP6xWgL91Jn-hrqg5QObfCZA%40mail.gmail.com Kind Regards, Peter Smith.
