Hi,

A comments on the v26 patch.

The following document about pg_stat_subscription_stats view only says that
"showing statistics about errors", should we add something about transactions
here?

<row>
<entry><structname>pg_stat_subscription_stats</structname><indexterm><primary>pg_stat_subscription_stats</primary></indexterm></entry>
<entry>One row per subscription, showing statistics about errors.
See <link linkend="monitoring-pg-stat-subscription-stats">
<structname>pg_stat_subscription_stats</structname></link> for details.
</entry>
</row>

I noticed that the v24 patch has some changes about the description of this
view. Maybe we can modify to "showing statistics about errors and transactions".

Regards,
Shi yu
