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. -- View this message in context: http://www.postgresql-archive.org/BUG-14680-startup-process-on-standby-encounter-a-deadlock-of-TwoPhaseStateLock-when-redo-2PC-xlog-tp5964069p5964796.html Sent from the PostgreSQL - bugs mailing list archive at Nabble.com. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
