Re: Add publisher and subscriber to glossary documentation.

Here are some comments for patch v3:

1.
+  <glossentry id="glossary-publication-node">
+   <glossterm>Publication node</glossterm>
+   <glossdef>
+    <para>
+     A <glossterm linkend="glossary-instance">node</glossterm> where a
+     <glossterm
linkend="glossary-publication">publication</glossterm> is defined
+     for <glossterm linkend="glossary-replication">logical
replication</glossterm>.
+    </para>
+   </glossdef>
+  </glossentry>
+

I felt the word "node" here should link to the glossary term "Node",
instead of directly to the term "Instance".

2.
+  <glossentry id="glossary-subscription-node">
+   <glossterm>Subscription node</glossterm>
+   <glossdef>
+    <para>
+     A <glossterm linkend="glossary-instance">node</glossterm> where a
+     <glossterm
linkend="glossary-subscription">subscription</glossterm> is defined
+     for <glossterm linkend="glossary-replication">logical
replication</glossterm>.
+    </para>
+   </glossdef>
+  </glossentry>
+

(same comment as above)

Apart from those links, it looks good to me. Let's see what others think.
