Thanks for your new patch. Here are some comments on v23 patch.

1. doc/src/sgml/ref/alter_publication.sgml
+ <para>
+ Add some schemas to the publication:
+<programlisting>
+ALTER PUBLICATION sales_publication ADD ALL TABLES IN SCHEMA marketing_june, sales_june;
+</programlisting>
+ </para>

This change seems to be added twice, both 0003 and 0004 patch have this change.

2. src/sgml/ref/create_publication.sgml
There is the following description about "FOR TABLE" parameter:
Only persistent base tables and partitioned tables can be part of a
publication. Temporary tables, unlogged tables, foreign tables,
materialized views, and regular views cannot be part of a publication.

"FOR ALL TABLES IN SCHEMA" parameter also have restrictions, should we add
some doc description for it?

3. When using '\dn+', I noticed that the list of publications only contains the
publications for "SCHEMA", "FOR ALL TABLES" publications are not shown. Is it designed on purpose?
(The result of '\d+' lists the publications of "SCHEAME" and "FOR ALL TABLES").

For example:
create schema sch1;
create table sch1.tbl(a int);
create publication pub_schema for all tables in schema sch1;
create publication pub_all_tables for all tables;

postgres=# \d+ sch1.tbl
Table "sch1.tbl"
Column | Type | Collation | Nullable | Default | Storage | Compression | Stats target | Description
--------+---------+-----------+----------+---------+---------+-------------+--------------+-------------
a | integer | | | | plain | | |
Publications:
"pub_all_tables"
"pub_schema"
Access method: heap

postgres=# \dn+ sch1
List of schemas
Name | Owner | Access privileges | Description
------+----------+-------------------+-------------
sch1 | postgres | |
Publications:
"pub_schema"
