What can be more important in the data load process than speed? Data migration is one of the most requested features in DBeaver. So the performance issue was highly important for us, in regard to PostgreSQL, as well as Greenplum, Redshift and other Postgres-based databases. We are ready to share our tiny secrets about 10x, 100x, 1000x, and even 10,000x performance improvements for data imports without any magic.

Narrow way to four nines. Postgresql clusterin in virtual environment - why's and how's. Why Corosync/Pacemaker? What about backups? Difficulties, problems and how to avoid them.

The development of secure system software (like an operating system or a DBMS) and ensuring trust in it are complicated scientific and technical tasks. In our presentation, we will demonstrate how we resolved these tasks for the Astra Linux OS certified to comply with the highest security classes. We will discuss the key directions of our activities, from the formation of national standards to the development and verification of the formal access model, which is the basis for the attack surface protection mechanism on the OS's level. We will also share how we apply the methods and technologies of dynamic and static analysis of the program code and, finally, we will explain how we collect and analyze the data we get from analyzing the OS code. We will also discuss how to fix the code errors in the project with continuous integration.

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.
