Hi Vignesh, Here are a few small review comments just for the docs
part of patch 0001:

======
Commit message

1.
In addition to the new command, the following subscription commands have
been enhanced to automatically refresh sequence mappings:

~

Is "mappings" the right word?

          <para>
-          When false, the command will not try to refresh table information.
-          <literal>REFRESH PUBLICATION</literal> should then be
executed separately.
-          The default is <literal>true</literal>.
+          When false, the command will not try to refresh table and sequence
+          information. <literal>REFRESH PUBLICATION</literal> should then be
+          executed separately. The default is <literal>true</literal>.
          </para>

I thought false should use markup: <literal>false</literal>  (just
like true does)

+         <para>
+          Previously subscribed sequences are not re-synchronized. To do that,
+          see <link linkend="sql-altersubscription-params-refresh-sequences">
+          <command>ALTER SUBSCRIPTION ... REFRESH SEQUENCES</command></link>.
+         </para>

/To do that, see/To do that, use/

4.
+     <para>
+      Re-synchronize sequence data with the publisher. Unlike
+      <link linkend="sql-altersubscription-params-refresh-publication">
+      <literal>ALTER SUBSCRIPTION ... REFRESH
PUBLICATION</literal></link> which
+      only synchronizes newly added sequences, <literal>REFRESH
SEQUENCES</literal>
+      will re-synchronize the sequence data for all subscribed sequences. It
+      does not add or remove the missing publication sequences from the
+      subscription.
+     </para>

4a.
IMO the ALTER SUBSCRIPTION command should have <command> markup
instead of <literal>

~

4b.
I wondered if that part "...for all subscribed sequences" should say
"...for all currently subscribed sequences", just for more clarity.

~

4c.
I do not think you need to say "the missing" here; IMO, that just
leads to more questions -- missing from where? How do you remove
something that is missing? etc. The suggestion below removes the
ambiguity.

SUGGESTION:
It does not add or remove sequences from the subscription to match the
publication.

Kind Regards,
