By the way, I notice that in 002_types.pl (on master branch), it seems the "as
well" in the following comment should be removed. Is it worth being fixed?

$node_subscriber->safe_psql('postgres',
    "CREATE SUBSCRIPTION tap_sub CONNECTION '$publisher_connstr' PUBLICATION tap_pub WITH (slot_name = tap_sub_slot)"
);

# Wait for initial sync to finish as well
$node_subscriber->wait_for_subscription_sync($node_publisher, 'tap_sub');
