Maybe we should be promoting pgpool's replication in that light. "If you're looking something that works like MySQL's replication, use pgpool. If you want a much more sophisticated and complex mechanism, use Slony".

I'd say google:'mysql gotchas' is a pretty good indicator of that. ;) MySQL tries desperatly hard to make databases 'easy', but the reality is that unless it's a pretty trivial embedded database, databases (both RDBMSes and database design and use) aren't easy; they're probably one of the most complex pieces of IT in commmon use today. IMO, in trying to 'make it simple', a lot of people end up burned. -- Jim C.
