Real time replication of PG DBs accross two servers - any experiences?

Hi All,

I desperately need to set up a real time replication of several 
databases (for failover) between two servers. Last time I looked at the 
PG replication it wasn't yet production level. I wonder if anyone on 
this list is doing this successfully and if you won't mind sharing your 
experience and giving me any tips that you may think would be handy from 
a real world perspective I would very much appreciate it.

I am 100% Linux-based, in case that makes a difference! I have also 
considered using the CODA files system in case the replication isn't 
quite up to production levels still.

Thanks,

Brad
