Hi Michael,

appreciate for your quick response.

i look carefully on the patch, because of we removed TwoPhaseStateLock
lwlock acquire in `RemoveGXact' and let caller held lwlock, so i think:
1. xact_redo also need held lwlock before call PrepareRedoRemove
2. RecoverPreparedTransactions also need held lwlock before call
ProcessTwoPhaseBuffer
