Thanks for your patch. But there is a problem about "ALTER PUBLICATION … SET TABLE …", which is similar to the issue Greg reported at [1].

For example:

postgres=# CREATE TABLE public.t1 (a int);

CREATE TABLE

postgres=# CREATE PUBLICATION pub1;

CREATE PUBLICATION

postgres=# ALTER PUBLICATION pub1 SET TABLE public.t1;

ALTER PUBLICATION

postgres=# \dRp

                                    List of publications

Name |  Owner   | All tables | Inserts | Updates | Deletes | Truncates | Via root | PubType

------+----------+------------+---------+---------+---------+-----------+----------+---------

pub1 | postgres | f          | t       | t       | t       | t         | f        | e

(1 row)

I think PubType in this case should be 't' instead of 'e'. Please have a look.
