HI all, I'm trying to implement a highly-scalable, high-performance,
real-time database replication system to back-up my Postgres database
as data gets written.

So far, Mammoth Replicator is looking pretty good but it costs $1000+ .  

Has anyone tried Slony-I and other replication systems?  Slony-I is
pretty new so I'm a little unsure if it's ready for a prime-time
commercial system yet.

So... wanted to put this out to the experts.  Has anyone got any
recommendations or had experiences with real-time database replication
solutions that don't rely on RAID?  The reason why I don't want to
rely on a hardware solution is because we are renting dedicated
servers and we don't have access to the boxes, only to software that
gets installed on the boxes.

TIP 9: the planner will ignore your desire to choose an index scan if your
      joining column's datatypes do not match
