[Spacewalk-list] Replicate spacewalk core to another data center for HA

[Paul Robert Marino]

Well in that case I still would like to avoid slony if possible
I would prefer using the native postgresql master slave replication with
pgpool but I would need dig into the sql queries a bit to figure out how I
would want to configure the load ballancing also I'm not sure I need to
double check but I think there is a way in potstgresql 9 to do more
specific targeting of the replication
