Re: Skipping schema changes in publication

Hi Shlok.

Some questions for the patch v25-0002 (EXCEPT tables)

======
doc/src/sgml/ref/alter_publication.sgml

1.
+ALTER PUBLICATION <replaceable class="parameter">name</replaceable>
ADD ALL TABLES [ EXCEPT [ TABLE ] ( <replaceable
class="parameter">exception_object</replaceable> [, ... ] ) ]

You can do both ADD/SET the <publication_object>, so really there
should be an ADD/SET ALL TABLES command as well, right?

2.
What was your reason for changing the syntax?
AFAICT those added "( )" are not strictly necessary, so I just
wondered your reason.

For example, we do not have any "( )" for <publication_object> [,...].
It is: ALTER PUBLICATION name ADD publication_object [, ...]
Not:   ALTER PUBLICATION name ADD (publication_object [, ...])

So in the same way we could have EXCEPT syntax like that:
ALTER PUBLICATION name ADD ALL TABLES [EXCEPT <table_exception_object> [, ...]]
Where table_exception_object is: [ TABLE ] [ ONLY ] table_name [ * ]

Currently, if the user just wants to exclude a single table they must do:
ALTER PUBLICATION name ADD ALL TABLES EXCEPT (t1);
instead of just ALTER PUBLICATION name ADD ALL TABLES EXCEPT t1;

~~~

3.
BTW, I think you may need to consider a <table_exception_object>
instead of a generic name like <exception_object>, because in the
future if we EXCEPT SEQUENCES the <exception_object> name may be not
appropriate because things like [ONLY] and [*] are not applicable for
sequences.
