Michael Paquier 7b8c2de64e Fix race condition at backend exit when deleting element in syncrep queue ... When a backend exits, it gets deleted from the syncrep queue if present. The queue was checked without SyncRepLock taken in exclusive mode, so it would have been possible for a backend to remove itself after a WAL sender already did the job. Fix this issue based on a suggestion from Fujii Masao, by first checking the queue without the lock. Then, if the backend is present in the queue, take the lock and perform an additional lookup check before doing the element deletion.
