I see...
I checked part of HOT patches(patch1), and found that it involves too
many things I am not currently familar with. Maybe I should change an
item to work. :-(
Since I only studied part of source codes about transaction
processing(lmgr/MVCC/xact  but without xlog.c),  I want to study
"Group Commit" patch and try to review it, any suggestions?

Right.  The reason the patch was kept in the queue is that there was
discussion that HOT will exercise that part of the code a lot more than
it does currently.
