Or you can use the p_usrloc module that does automatically the db 
replication and failover + data partitioning (or you can combine them to 
suite your needs). New in master branch (</shameless advertisement>)

But seriously, we might want to give it a try. The config syntax remains 
the same as above you just need to load p_usrloc instead of usrloc and 
setup the databases.
