   while ((entry = (PendingOperationEntry *) hash_seq_search(&hstat)) != 
NULL)
   {
+   if (i >= count)
+    elog(ERROR, "pendingOpsTable corrupted");
+
+   memcpy(&entries[i++], entry, sizeof(PendingOperationEntry));
+
+   if (hash_search(pendingOpsTable, entry,
+       HASH_REMOVE, NULL) == NULL)
+    elog(ERROR, "pendingOpsTable corrupted");
+  }

What's the rationale of this change?
