5 steps to implement a PostgreSQL replication system

Yesterday, I tried to build a PostgreSQL master-slave replication system with new feature "Streaming Replication (SR)", which is coming in the next PostgreSQL major release 9.0 as a built-in replication solution, and it worked well on my servers.

I feel it is very easy to configure, so I have decided to make some memos here for building a PostgreSQL master-slave replication system.

Here are 5 steps to implement a PostgreSQL replication system.

1. Build and install binaries.
2. Initialize a database cluster and duplicate it.
3. Configure the master node.
4. Configure the slave node(s).
5. Start the master and slave node(s).

Ok, let's start.
