-    if (walsndctl->lsn[SYNC_REP_WAIT_WRITE] < MyWalSnd->write)
+    if (is_highest_priority_sync_standby)

[ ... ]

-    if (walsndctl->lsn[SYNC_REP_WAIT_FLUSH] < MyWalSnd->flush)
-    {
-        walsndctl->lsn[SYNC_REP_WAIT_FLUSH] = MyWalSnd->flush;
-        numflush = SyncRepWakeQueue(false, SYNC_REP_WAIT_FLUSH);

[ ... ]

+        if (walsndctl->lsn[SYNC_REP_WAIT_FLUSH] < MyWalSnd->write)
+        {
+            walsndctl->lsn[SYNC_REP_WAIT_FLUSH] = MyWalSnd->flush;
+            numflush = SyncRepWakeQueue(false, SYNC_REP_WAIT_FLUSH,
+                                        MyWalSnd->flush);

There seems to be a copy-pasto there - shouldn't that be:

+ if (walsndctl->lsn[SYNC_REP_WAIT_FLUSH] < MyWalSnd->flush)

Thanks,
Amit
