Can someone more versed in the current state of Postgres chime in on something for me? > "One use case that has historically been challenging in database management is setting up a read replica, often referred to as a read slave." Having only inherited MySQL stuff in production, this is pretty trivial in MySQL land - I was under the impression that Postgres also had a solution for this, with Slony and recently as a part of Postgres core. Is my info wrong on this? I thought master/slave replication was a pretty solved problem at this point, am I wrong?
