PostgreSQL could easily be named the master of indexes - there is no other database that could compete with Postgres for the variety of indexes. How developers can use this advantage effectively in their day to day work? How do you know which index to create? When the created index might slow our application’s performance? We will try to get our head around this topic with some use cases and live examples. This talk would be of interest for any developer who wants to expand their knowledge of indexes in Postgres and secure the best performance for their application.

PostgreSQL maintenance without backups is unacceptable. The constant growth of PostgreSQL clusters in maintenance creates new issues and bottlenecks for the chosen backup scenario. In this presentation, we will explain how to efficiently use pg_probackup under such circumstances.

Crew Resource Management is a field which has become critical in many fields including aviation and nuclear power. However in IT, this field has not been well implemented. In this talk we will discuss what crew resource management is, what kinds of problems it solves, and why all database teams should implement it.

Several PostgreSQL-related case studies will be discussed and both technical and human factors will be part of the case studies.

PostgreSQL protocol compression has been discussed in the community for a long time. Many different hypotheses have been expressed and tested, and the compression patch has received a large number of changes and improvements. I will review the various approaches tested during the implementation of protocol compression, and will highlight the current status.
