I'll send you a URL as soon as I have it online. If I take too much
time, send me an email again. Give me a few days, though.

 think there are better ways ;-)

No. It means you want to use WAL archiving to archive logs, then
transfer them, then use PITR so that, when the node being recovered is
starting, it reads those WAL files and processes them to bring itself
back to speed with the master node.

I strongly suggest that you read the online documentation at
postgresql.org regarding WAL and PITR before getting started with
pgpool. It's not easy, but it's a must that you understand it. Still,
you don't really need to use PITR. It's an improvement IMHO, but not a
requirement.
