I had no idea someone was working on WAL-log-based replication; I saw
the TODO entry a while ago, but I missed the thread. I think WAL
replication is a beautiful idea, so I'll gladly throw my support
behind this. Thanks for the pointer.

pgpool-II seems like a decent idea. I'm not sure if the partitioning
can support referential integrity though -- would they have to be
declared as CHECK constraints that used dblink()?
Also, it doesn't seem capable of planning a query intelligently, which
means that a query such as "select * from foo where id = 123" is going
to be aggregated across all nodes even though only one node has the
partition covering the id range [0, 1000], say.
