+
+Wait for all tables in pg_subscription_rel to complete the initial
+synchronization (i.e to be either in 'syncdone' or 'ready' state).
+
+If the publisher node is given, additionally, check if the subscriber has
+caught up to what has been committed on the primary. This is useful to
+ensure that the initial data synchronization has been completed after
+creating a new subscription.
+
+If there is no active replication connection from this peer, wait until
+poll_query_until timeout.
+
+This is not a test. It die()s on failure.
