I'm sorry for late my response.
I already sent same contents to Marcos, but I did not cc to all of yours.
(I'll join pgsql-hackers ML).
1. Statement of PGCluster-II
The state of PGCluster-II is re designing.
I developed and demonstorated PGCluster-II as full data shared model in 2006.
It worked fine.
However, perfomance point of view, it was not good at all.
Then, I improved it in 2007. Even so, it was absurdly slow.
I think that it was required redesigning to improve performanse.
The full data shread model is not difficult to build up (I developed the 1st PGCluster-II within 2 weeks),
but it is not easy to improve performanse.
Then, I chose partial data shared model as my conclusion.
I spend two years to decide it.
2. Prospects of PGCluster-II
Currentry, I'm developing the cluster server management tools as a part of the latest PGCluster.
It will be upcoming release.
After that, I will be back to the PGCluster-II project.
On comming Nov. 19, The International PostgreSQL Cluster Developper's Meeting (I'm not sure the proper name) will be
heldin Tokyo.
I'll discuss about a task of PGCluster-II as a part of PostgreSQL's cluster project at the meeting.
Clustering is getting more important each day.
I'm expecting that PGCluster & PGCluster-II play a role in the solution.
Best regards,
