Back-Patch "Add wait_for_subscription_sync for TAP tests."
This was originally done in commit0c20dd3 for 16 only, to eliminateduplicate code and as an infrastructure that makes it easier to writefuture tests. However, it has been suggested that it would be good toback-patch this testing infrastructure to aid future tests inback-branches.Backpatch to all supported versions.Author: Masahiko SawadaReviewed by: Amit Kapila, Shi yuDiscussion:https://postgr.es/m/CAD21AoC-fvAkaKHa4t1urupwL8xbAcWRePeETvshvy80f6WV1A@mail.gmail.comDiscussion:https://postgr.es/m/E1oJBIf-0006sw-SA@gemulon.postgresql.org

Wait for all tables in pg_subscription_rel to complete the initial
2092+
synchronization (i.e to be either in 'syncdone' or 'ready' state).
2093+
2094+
If the publisher node is given, additionally, check if the subscriber has
2095+
caught up to what has been committed on the primary. This is useful to
2096+
ensure that the initial data synchronization has been completed after
2097+
creating a new subscription.

If there is no active replication connection from this peer, wait until

This is not a test. It die()s on failure.
