Future Postgres Challenges
Postgres has been a vibrant project for decades, and probably will be popular for decades to come. However, as with any complex endeavor, challenges are always lurking. This talk explores the many project, competitive, and technical challenges in the future that could derail its success. By exploring these challenges, we will be better able to avoid them.

Several production cases during one night
We maintain large PostgreSQL databases with the total data volume exceeding 180 TB. Every instance in the cluster gets a workload of 15 thousand requests per second. These circumstances certainly impose limitations on the classical approach to updating database structures. The cost of a DBA error gets higher, as even a small error can lead to a sleepless night) In my talk, I will cover our existing limitations for changes in the production environment, non-classical DBMS behavior under heavy workloads, and will discuss PostgreSQL in general.

Unequal battle with "bloating" in the realities of 1C databases
Data is getting bigger, disks are getting faster, the DBMS optimizer is getting smarter, but the problem of " bloating " remains extremely relevant. I want to share my experience and approach to dealing with this effect on a large number of tables and data in them.

Why do we need 64-bit transaction IDs?
When PostgreSQL was at its formation stage, its transaction ID was chosen to be 32-bit. Back then, no one could imagine that someday we may need more than 4 billion transactions. However, ongoing technical progress and digitization pushed some Postgres instances towards their transaction ID limit. The Postgres community reacted to this with a wraparound of the transaction ID counter. However, constantly growing data volumes exposed PostgreSQL to new challenges. In my presentation, I will cover these challenges and explain how they can be solved with a 64-bit transaction ID, what the consequences will be like, why now it is a good time to implement 64x IDs, and why this hasn't been done previously.

PostgreSQL certification: personal experience of taking four tests
In May 2019, Postgres Professional launched the PostgreSQL certification program. I have been working in this company since March 2020, and in a year I have successfully taken four tests on the DBA1, DBA2, DBA 3, QPT courses. In this talk, I will share my experience of preparing for the exams and passing these tests.
