Fresh copy of a PG DB ?

[Pascal Heraud <heraud(at)tatm(dot)com>]

Hello all,

I want to have a fresh copy of my postgres database on another server in 
order to provide a simple mechanism of failover.
My current solution is to backup the database every hour and re-create 
from scratch on the other side.

Currently the database is small and its not an issue but when the size 
will be bigger, it can become an issue as you can guess :)

What are the other solution to provide this service in a incremental 
manner ? Is there any "dupplication" tool or mechanism provided to allow 
such a repplication ?

We looked at the way of using a replication solution but it seems very 
coupled to the version of the database we use. We are using PGSQL 8.2.4 
on a Gentoo Linux OS.

Thanks for any clue :)

Pascal
