I checked the latest v9-0001 patch. Below are my review comments.
Other than these few trivial comments this 0001 patch looks good to me.
~~~
1. src/backend/replication/pgoutput/pgoutput.c - whitespace
@@ -1696,6 +1714,10 @@ static bool

Suggest to add a blank line after the return true;

2a. AFAIK the code intended that these options be listed in
alphabetical order (I think the recent addition of disable_on_error is
also wrong here). So "local_only" should be moved.

The new test looked good, but the cut/paste text message ('Inserted
successfully without leading to infinite recursion in circular
replication setup') maybe needs changing because there is nothing
really "circular" about this test case.
