[BUGS] Re: BUG #14680: startup process on standby encounter a deadlock ofTwoPhaseStateLock when redo 2PC xlog

Hi, Michael

I don't understand why the patch remove TwoPhaseStateLock in MarkAsPrepared.

if so:
1. does it need remove lock acquire in MarkAsPreparing also?
2. MarkAsPrepared will call ProcArrayAdd, and in ProcArrayAdd it acquires
ProcArrayLock, we should carefully handle the lock sequence about these two
locks.
