Previously, during a promotion, only the slot synchronization worker was signaled to shut down. The backend executing slot synchronization via the pg_sync_replication_slots() SQL function was not signaled, allowing it to complete its synchronization cycle before exiting. An upcoming patch improves pg_sync_replication_slots() to wait until replication slots are fully persisted before finishing. This behaviour requires the backend to exit promptly if a promotion occurs. This patch ensures that, during promotion, a signal is also sent to the backend running pg_sync_replication_slots(), allowing it to be interrupted and exit immediately.
