Hi men :-)
Just one question for those of you who have spent many time with postgres.
I want to create a load balancing and High Availability system with two
This two server have a common hard disk: A RAID 5 server connected to them
by the LAN.
I have a hardware machine (WSD+ from RADWARE) that manages the load
I want to have, two servers, and two postgres installations, one in each
server, but with a  common PGDATA directory in the RAID.
So, if one of the servers crashes, people can still get the information from
the other server.
Esentially, what I want is, two postgres (one in each machine) with a shared
PGDATA directory, and that both postgres can access and do Inserts in the
tables, and when one postgres does an insert, the second sees what the first
has inserted.
