Hi, ioseph, 

I took a look at the doc part and have two comments.

/doc/src/sgml/ref/pg_createsubscriber.sgml
1. "The default is <literal>false</literal>" , it'd be better to add "value" after the "default". 

2. I think the following content should be surrounded by <para> and </para>, so the <para> should be moved to be in front of "When this option is enabled..."

+       When this option is enabled, the connection string used in the <option>--publisher-server</option>
+       option may be adjusted to support failover. For example, by specifying multiple hosts 
+       and using <literal>target_session_attrs=read-write</literal>.
+      <para>
+      </para>
+     </listitem>
+    </varlistentry>
Thanks,
Xueyu Gao
