The talk aims to present pgpool-II to the largest audience. One part of the attendees will hear about pgpool-II maybe for the first time. So I'll present what it is, and its features. Other part of the attendees that already use or know pgpool-II will learn the very last thnigs about pgpool-II, and how to use it in conjuction with a cluster PostgreSQL 9.0 servers replicated in Streaming Replication and using Hot Standby. This way I hope newcomers and users will both have interest in this talk.
