PGConf.Russia 2025

In 2024, Postgres Professional introduced pgpro-otel-collector, a new tool for gathering PostgreSQL telemetry data using OpenTelemetry technologies and standards.

In this talk, I’ll explain why we chose OpenTelemetry, showcase the features of pgpro-otel-collector, and demonstrate how it helps streamline telemetry collection within a monitoring infrastructure.

In this talk, I will challenge architectural stereotypes about the impossibility of communication with external systems directly from a DBMS. PostgreSQL offers vast communication capabilities; you just need to know which extensions to use.

And when extensions aren't enough, you can create your own. For the Luxms BI project, we needed communication with NATS, so we developed our own extension in Rust. I’ll share the GitHub link and my experience of developing PostgreSQL extensions in Rust during this talk.

The execution time of SQL queries depends on factors like indexes and up-to-date statistics. In most cases, optimizing slow queries helps resolve database performance issues.

But what if classic query optimization doesn’t work? What if the system keeps behaving unpredictably — or worse, crashes, leading to frustration, panic, and even despair?

In this talk, we’ll explore how Postgres Professional’s performance engineers tackle these challenges, look at the tools they use, what’s still missing, and where PostgreSQL performance optimization is headed

Over the past year, pgpro_redefinition has undergone significant enhancements. In this talk, we’ll review the key updates, improvements, and new capabilities that have been introduced.
