Hi Shubham, here are some more patch v8-0001 comments that I missed yesterday.
======
src/test/subscription/t/011_generated.pl
1.
Are the PRIMARY KEY qualifiers needed for the new tab2, tab3 tables? I
don't think so.
~~~
2.
+$result = $node_subscriber->safe_psql('postgres', "SELECT * FROM tab2");
+is( $result, qq(4|8
+5|10), 'confirm generated columns ARE replicated when the
subscriber-side column is not generated');
+
+$node_publisher->safe_psql('postgres', "INSERT INTO tab3 VALUES (4), (5)");
+
+$node_publisher->wait_for_catchup('sub3');
+
+$result = $node_subscriber->safe_psql('postgres', "SELECT * FROM tab3");
+is( $result, qq(4|24
+5|25), 'confirm generated columns are NOT replicated when the
subscriber-side column is also generated');
+
It would be prudent to do explicit "SELECT a,b" instead of "SELECT *",
for readability and to avoid any surprises.

Kind Regards,
