Thanks for updating the patch. A comment on the test in 0001 patch.

+# Alter subscription ... refresh publication should fail when a new table is
+# subscribing data from a different publication should fail
+($result, $stdout, $stderr) = $node_A->psql(
+ 'postgres', "
+ ALTER SUBSCRIPTION tap_sub_A2 REFRESH PUBLICATION");
+like(
+ $stderr,
+ qr/ERROR: ( [A-Z0-9]+:)? could not replicate table "public.tab_new"/,
+ "Create subscription with origin and copy_data having replicated table in publisher"
+);

The comment says "should fail" twice, the latter one can be removed.

Besides, "Create subscription with origin and copy_data" should be changed to
"Alter subscription with origin and copy_data" I think.

Regards,
Shi yu
