The ideal scenario is 2 identical servers sitting behind 1 ip adress. The user 
uses this ip as POSTGIS server and couldn't even know if its geodatabase 
service is server by 1 postgis or two or three (i used to work for a non gis 
app with oracle RAC and i thought it would be possible to do something similar 
with postgres+postgis).
I thought that pgpool II could do this for me, but I'm not aware how this could 
work with POSTGIS.I can also use a master server replicated (with postgres 
streaming replication) on a second server which is used only for querying but i 
want to know what happens if master dies. Does the replica become a new master 
trasparently for the clients or do they have to connect to a different ip?
The GIS data that i except to manage are 10gb in several tables. I also expect 
that the user wants to creare in the POSTGIS server new geographic tables.
Thanks for any advice!!!
