Streaming replication has been introduced in 2010 and quickly became one of the most popular features of PostgreSQL. Today, it is hard to imagine PostgreSQL installation without streaming replication. With its stability, high efficiency and ease of configuration one would have thought it is an optimal feature. However, while using it you might sometimes enter murky waters. This often can be resolved by using a combination of built-in and third party troubleshooting tools. In my talk I will provide an overview of these tools and explain how with their help one can diagnose, understand and eliminate problems related to streaming replication. I will also go through the most frequent issues occurring when streaming replication is used and will propose possible solutions. This talk is primarily aimed at DBAs and system administrators who use PostgreSQL in their day-to-day.

Modern state of backup tools for PostgreSQL certainly leaves some room for improvements. Standard utilities provides only basic functionality, third-party tools solve some, but not all, problems. To take backups reliably, fast, and incrementally on page level, one needs not only a backup tool, but also some support from the database server. On this tutorial we will talk about our new backup and recovery manager ProBackup, and will show it in action.
