Hi,

Please include all known information about how this feature looks from
the user's POV.

Ideally, this information should be in the form of PGDOCS updates
included in patch 00001.

I think documenting these details should not be deferred - reviewers
will want to experiment with the feature, and also to be able to
consider about any behaviour pros/cons.

e.g. I can guess from the patch 0004 test cases maybe it currently
looks like this:

CREATE PUBLICATION mypub FOR ALL TABLES with (publish = 'insert,
update, delete, ddl')

But without documented details, that just raises more questions:

e.g.
- Does it mean the DDL replication all-or-nothing? What if I only want
to create missing tables, but not everything else?
- Is 'ddl' publish option able to be specified when using CREATE
PUBLICATION ... FOR ALL TABLES?
- What if I want to replicate DDL but not data (e.g. for making an
empty "test" database)? Will just saying publish='ddl' allow that?
- etc.

Kind Regards,
