I don't know if it's de-facto, but it's the only free solution that I
found that was reasonably designed. The other ones seem to be
synchronous or otherwise unreliable-by-design. As far as case studies
go, Slony-I was originally developed by Afilias (the registrar for the
".info" TLD), and I'm relativley certain it's involved in most of
their business-criticial apps for replication and load balancing.

Interestingly, I first found out about it at BSDCan 2004 :)
