Creation of a completely import-substituted component of the state information system using the example of the PUR KS - the "Electronic Budget" subsystem, the key state integrated information system for managing public finances. The presentation presents the subsystem architecture, performance optimization history and monitoring description. The speaker will talk about the advantages and difficulties of using an import-substituted system for the public sector, as well as about the nuances that departments should take into account when implementing open source solutions and solutions from Russian developers.

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.

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.

Intel® Xeon® Scalable Gen 3 - new commands have been added to speed up the database: vector bit manipulation instructions to enable data compression without losses, vector instructions to make TLS protocols faster and SGX enclaves for secure code execution. We will also discuss the new generation of persistent memory Intel® Optane™ PMem 200 series. We will explain what these new technologies including oneAPI tools can give to the PostgreSQL project community
