Attached are some proposed documentation updates (to be applied ontop of
your 20161031 patch set)
Also

Is renaming of tables any less supported than other DDL operations
For example
alter table nokey2 rename to nokey3
select * FROM pg_publication_tables ;
pubname | schemaname | tablename
---------+------------+-----------
tpub | public | nokey3
(1 row)
If I then kill the postmaster on my subscriber and restart it, I get
2016-11-13 16:17:11.341 EST [29488] FATAL: the logical replication
target public.nokey3 not found

but if I then rename the table on the subscriber everything seems to work.
(I suspect the need to kill+restart is a bug, I've seen other instances
where a hard restart of the subscriber following changes to is required)
I am also having issues adding a table to a publication ,it doesn't seem
work
P: create publication tpub for table a;
S: create subscription mysub connection 'host=localhost dbname=test
port=5440' publication tpub;
P: insert into a(b) values ('1');
P: alter publication tpub add table b;
P: insert into b(b) values ('1');
P: insert into a(b) values ('2');
select * FROM pg_publication_tables ;
pubname | schemaname | tablename
---------+------------+-----------
tpub | public | a
tpub | public | b
but
S: select * FROM b;
a | b
---+---
(0 rows)
S: select * FROM a;
a | b
---+---
5 | 1
6 | 2
(2 rows)
