Subject: [PATCH v8 4/4] Add EXCEPT support to ALTER PUBLICATION SET TABLES IN
SCHEMA
Extend AlterPublicationExceptTables() with the AP_SetObjects case,
which redefines the publication and replaces the entire EXCEPT list.
Syntax:
ALTER PUBLICATION pub SET TABLES IN SCHEMA s EXCEPT (TABLE t1);
This patch also cleans up EXCEPT entries when a schema is dropped
from the publication.
