Thanks. Do you think we should restrict this case too? To me, this
seems like another variation of the above where conflicting entries
are given at the time of sub-creation itself. The root is excluded but
parittion is included .

postgres=3D# create publication pub1 for table s2.tab_part_1, tables in
schema s2 except (table tab_root);
CREATE PUBLICATION
postgres=3D# \dRp+
                                                      Publication pub1
 Owner  | All tables | All sequences | Inserts | Updates | Deletes |
Truncates | Generated columns | Via root | Description
--------+------------+---------------+---------+---------+---------+-------=
----+-------------------+----------+-------------
 shveta | f          | f             | t       | t       | t       | t
        | none              | f        |
Tables:
    "s2.tab_part_1"
Tables from schemas:
    "s2"
Except tables:
    "s2.tab_root"

thanks
