Talk Description: Streaming Replication, the basics

Streaming Replication can be used to setup a replicated PostgreSQL cluster, with one or more standby servers ready to take over operations if the primary server fails. This feature relies on the Write Ahead Logs, aka WALs, and offers a lot of possibilities. The talk will summarize for beginners what WALs are, how does the Streaming Replication works, give some advices and best practices.
