Optimisation of queries can have a significant impact on database performance. In my talk, I will review the tools that we use in our practice and discuss some use-cases.

Mamonsu is an active monitoring agent for PostgreSQL based on Zabbix. Mamonsu 3.0 Major Update includes new metrics and more possibilities for data visualization via Zabbix screens. It also introduces the improved functionality of Mamonsu tools for interacting with the DBMS.

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.

Throughout the release cycle of version 14, I had the opportunity to describe the accepted patches in articles dedicated to each of the five release commitfests. The first two articles on Postgres 15 also have some remarks on PostgreSQL 14. If you have read them, you can skip my presentation :-)). On September 30, 2021, PostgreSQL 14 was officially released. Nothing will change in this major release, so it's the right time for a final overview. However, presenting each and every new feature in a 45-min. talk isn't possible. That's why I will be sharing with you my personal top of version 14 innovations.
