The latest patch LGTM regarding the content.
But, there were some trivial issues.
======
1.
The patch name did not change. The 2nd patch was still called 0001?
~~~
2.
+ <para>
+ The <structname>pg_stat_replication</structname> view will contain one row
+ per WAL sender process, showing statistics about replication to that
... etc.
Paragraph text is sometimes indented 1 space too many in the SGML file.
AFAIK, text normally is aligned with the "p" of <para>.

Kind Regards,
