  1. Honor run_as_owner option in tablesync worker.

  2. Document new pg_subscription columns.

  3. Add a run_as_owner option to subscriptions.

  4. Perform logical replication actions as the table owner.

  5. Add new predefined role pg_create_subscription.

  6. Respect permissions within logical replication.

  7. Empty search_path in logical replication apply worker and walsender.

  8. Empty search_path in Autovacuum and non-psql/pgbench clients.
