I think what Tom was saying is that the PostgreSQL Inc version is
production-ready-ish right now. It's sort of expensive, and it's a
pain in the neck to administer (and has some real annoying behaviour
under a couple of conditions), but if you're dealing with any volume,
it's what you should use today.
That isn't to say you should use it forever. There was some mighty
interesting work being done on dbmirror (several related questions
showed up on -hackers), and if you want to be sure that you replay
_every_ transaction to your slave, I gather it's the only way to go.
The contrib/rserv code does indeed work for some people, and it is
useful. It is nowhere close to handling large volumes, but for fewer
than a few thousand writes an hour, it seems to be good.
I haven't tried the other systems that are out there.
