I'd like to know what's your progress of choosing the cluster/grid solution, we are also looking for
an appropriate one, following is the our major factors of the ideal solution.

1. Some kind of MPP.
2. No single point of failure.
3. Convenient and multiple access interfaces.

And following the is the solutions we have examined:

1. Slony-I: Not a MPP solution, and using triggers to detect changes, which defects performance.
2. pgpool-II: Some kind of MPP, but join operations can't be done on multiple machines parallelly, that is it can't scale out well.
3. Sequoia : The same problem as pgpool-II, and the major access interface is JDBC.
