In Moscow took place the anniversary fifth official conference of the Russian community of PostgreSQL

Conferences PG BootCamp Russia have a confirmed official international status of community events of PostgreSQL and traditionally serve as platforms for exchange of experience, discussion of current technological challenges, and formation of a professional community around the popular open-source DBMS. The program is formed around real-world problems, developments, approaches, and cases which are shared by speakers. The selection of reports is handled by the Program Committee, which ensures that into the program do not end up overtly commercial or marketing materials; in other words, the focus of the conference — on open open-source developments.

The meeting was opened by members of the organizing committee of PG BootCamp Vadim Yatsenko (General Director of Tantor Labs) and Andrey Borodin (PostgreSQL major contributor, head of the development division of open-source RDBMS at Yandex Cloud). A message was delivered from Bruce Momjian, co-founder and member of the core team of the global group of developers of PostgreSQL, who highly appreciated the contribution of Russian developers to the development of the open-source DBMS.

In the program were presented 25 reports, covering a wide range of topics from the internal structure of the DBMS to the practice of operation of high-load systems and modernization of architecture. Opened the conference Andrey Borodin with a report "Archive of the Future," in which he examined in detail the mechanisms of preserving database history (point-in-time recovery). The speaker analyzed existing tools, including archive_command and restore_command, as well as new archive modules, outlining their limitations and possible directions of development.

The theme of optimization was continued by a developer from Yandex Alena Rybakina, having presented an analysis of alternative approaches to the work of the query optimizer. In the report were examined genetic algorithms, methods of machine learning and neural network models, their effectiveness on benchmarks, and prospects of application in industrial systems.

Architectural limitations of PostgreSQL and ways of their overcoming became the central theme of the presentation of the General Director of Tantor Labs Vadim Yatsenko. The report was devoted to practical approaches to solving problems of horizontal scaling, degradation of performance with a large number of connections, bottlenecks of the write-ahead log, and difficulties of parallel execution of queries. This theme was developed by architect and tech lead of Tantor Labs Alexey Kopytov, having presented a report on the implementation of the technology of independent scaling of storage and computing as a key trend in the development of global and domestic DBMSs. Were examined the advantages of separating the subsystems of computing resources and data storage, including reduction of replication lag, elimination of duplication of data, possibility of elastic scaling, and implementation of full-fledged processing of mixed workloads (HTAP), especially in demand in the Russian corporate segment.

To the practical aspects of performance diagnostics was devoted the report of Candidate of Physical and Mathematical Sciences, PostgreSQL contributor Andrey Lepikhov from pgEdge, in which was presented the extension pg_track_optimizer. The solution allows identifying errors of the query planner before their influence on the system through analysis of discrepancies between expected and actual parameters of execution.

From the applied side, the theme of high-load systems was continued by the lead database architect of the company Tensor Kirill Borovikov, having drawn attention to the influence of client architecture on the performance of PostgreSQL. In the report were examined typical errors of application design, leading to degradation of the DBMS's work.

The final part of the conference was devoted to the internal mechanisms of PostgreSQL and the operation of large systems. Sergey Solovyov from Tantor Labs analyzed the structure of data grouping and the used strategies of execution, and the head of the Java development department of the Moscow Exchange Andrey presented a report on transaction isolation levels in PostgreSQL. Within the presentation were clearly demonstrated typical anomalies of concurrent access — "dirty read," "non-repeatable read," and "phantoms" — as well as their behavior under various isolation levels in a real installation of PostgreSQL.

In addition to the business program, PG BootCamp Russia 2026 became a platform for professional communication. Participants were able to ask questions to the speakers, discuss applied tasks, and exchange experiences with colleagues from the industry.

The conference confirmed its status as one of the key events in the Russian-speaking PostgreSQL community and outlined the main technological trends of DBMS development, including the movement toward cloud architectures and systems of mixed workload processing, increasing performance, and the creation of new scalable solutions.

PG BootCamp in Russia are conducted free of charge for participants thanks to partners which develop and optimize PostgreSQL for domestic business. This time, the general partner of the event was the Russian DBMS vendor company Tantor Labs.
