Message: Re: Support EXCEPT for TABLES IN SCHEMA publications
From b46bea926dfb201005201bbefda3716ba7a8beee Mon Sep 17 00:00:00 2001

Subject: [PATCH v7 1/3] Support EXCEPT clause for schema-level publications

Extend table exclusion support in publications to allow specific
tables to be excluded from schema-level publications using an
EXCEPT clause in CREATE PUBLICATION.

Supported syntax:
CREATE PUBLICATION <pub> FOR TABLES IN SCHEMA s EXCEPT (TABLE t1,...);
