Has anyone used DRDB (http://www.drbd.org/) with Postgres and can speak to its speed/value, specifically in its various replication modes ( http://www.drbd.org/users-guide/s-replication-protocols.html)?
It performs quite well for us. Reads are local so there's nothing different with performance there. Writes will probably become network bound, but we're mostly read-only, so haven't approached any limit there.
In terms of value..... well, raid-1 over a network for free seems like a good value for warm clustering to me.
