The problem with this glib answer is that we are talking about systems where such a "user bug" can cost people millions of dollars. They want the _machine_ to prevent the user bug. That's what they think they're buying, and my understanding is that some of the other systems provide greater protection. Remember, a five-nines system means five minutes of downtime, all told, per year. People who really need that are willing to pay for it, because it's worth it. Most of the time, it isn't, and most so called five-nines systems really aren't. (There is no way you could really claim reliable five nines performance on the in-memory-only MySQL system, for instance: it'd be too risky, unless you could guarantee you'd never exceed your memory. Who's willing to guarantee the data set won't grow unexpectedly?) That said, using pgpool for higher-reliability, we-checked-it-real- good systems isn't a bad idea; on the contrary. Just let's not pretend it's something that it isn't really.
