Hot Standby and prepared transactions

I get this when testing prepared transactions, which looks like it is
unrelated to Hot Standby.

This looks like the code is setting the parent to be zero. That
assertion wasn't added by the patch.

2-phase state file attached, zipped. I think we need some tools to
inspect state files.

Can you look at this please?
