Thanks for updating the patch.

Few comments:

1. 
I think we should add some doc for column stats_reset in pg_stat_subscription_activity view.

2.
+CREATE VIEW pg_stat_subscription_activity AS
     SELECT
-        w.subid,
+        a.subid,
         s.subname,
...
+        a.apply_error_count,
+        a.sync_error_count,
+	a.stats_reset
+    FROM pg_subscription as s,
+        pg_stat_get_subscription_activity(oid) as a;

The line "a.stats_reset" uses a Tab, and we'd better use spaces here.
