Subject: [PATCH v27 1/3] Add RESET clause to Alter Publication which will
reset the publication with default values.
This patch adds a new RESET clause to ALTER PUBLICATION which will reset
the publication to the default state. This includes resetting the publication
parameters, setting ALL TABLES and ALL SEQUENCES flags to false and dropping
the relations and schemas that are associated with the publication.
Usage:
ALTER PUBLICATION pub1 RESET;

From 5c2df3299f68d13666637dd071f66244013776b8 Mon Sep 17 00:00:00 2001

Subject: [PATCH v27 3/3] Skip publishing the columns specified in FOR TABLE
EXCEPT
A new "TABLE table_name EXCEPT (column_list)" clause for CREATE/ALTER
PUBLICATION allows one or more columns to be excluded. The publisher
will not send the data of excluded columns to the subscriber.
The new syntax allows specifying excluded column list when creating or
altering a publication. For example:
CREATE PUBLICATION pubname FOR TABLE tabname EXCEPT (col1, col2, col3)
or
ALTER PUBLICATION pubname ADD TABLE tabname EXCEPT (col1, col2, col3)
When column "prexcept" of system catalog "pg_publication_rel" is set
to "true", and column "prattrs" of system catalog "pg_publication_rel"
is not NULL, that means the publication was created with "EXCEPT
(column-list)", and the columns in "prattrs" will be excluded from
being published.
pg_dump is updated to identify and dump the excluded column list of the
publication.
The psql \d family of commands can now display excluded column list. e.g.
psql \dRp+ variant will now display associated "EXCEPT (column_list)" if
any.

Subject: [PATCH v27 2/3] Skip publishing the tables specified in EXCEPT TABLE.
A new "EXCEPT TABLE" clause for CREATE/ALTER PUBLICATION allows one or
more tables to be excluded. The publisher will not send the data of
excluded tables to the subscriber.
The new syntax allows specifying excluded relations when creating or altering
a publication. For example:
CREATE PUBLICATION pub1 FOR ALL TABLES EXCEPT TABLE (t1,t2);
or
ALTER PUBLICATION pub1 ADD ALL TABLES EXCEPT TABLE (t1,t2);
A new column "prexcept" is added to table "pg_publication_rel", to flag
the relations that the user wants to exclude from the publications.
pg_dump is updated to identify and dump the excluded tables of the publications.
The psql \d family of commands can now display excluded tables. e.g. psql
\dRp+ variant will now display associated "except tables" if any.
Bump catalog version.
