The TAP tests for logical replication in src/test/subscription are using
the following code in many places to make sure that the subscription is
synchronized with the publisher:
$node_publisher->wait_for_catchup('tap_sub');
$node_subscriber->poll_query_until('postgres',
qq[SELECT count(1) = 0
FROM pg_subscription_rel
WHERE srsubstate NOT IN ('r', 's')]);
The new function wait_for_subscription_sync() can be used to replace the
above code. This eliminates duplicated code and makes it easier to write
future tests.
