Thanks for the updated patch.

Currently there is one test to filter prepared txn with gid having
"_nodecode". I'm not sure if we can have any tests based on xid, I'm
sure you might have thought about it, Have you intentionally not
written any tests as it will be difficult to predict the xid. I just
wanted to confirm my understanding.
