If you hope, I can test this patch in DBT-2 benchmark in end of this week.
I will use under following test server.

* Test server
Server: HP Proliant DL360 G7
CPU: Xeon E5640 2.66GHz (1P/4C)
Memory: 18GB(PC3-10600R-9)
Disk: 146GB(15k)*4 RAID1+0
RAID controller: P410i/256MB

This is PG-REX test server as you know.
