PGConf.SPB 2023

Hardening is the process of strengthening the security of a system in order to reduce risks from possible threats. In my presentation, I will tell you how to protect service cluster communications using TLS connections, in order to avoid accidental or unauthorized access to Patroni's REST API and ETCD storage.

A story about practical approaches and tools for automating migration using 2 examples: a database with a structure change in the new version and a database with a significant content of the application's business logic.

In this talk, I will explain how you can organize account management in a microservice environment: organization of a role model, authentication via SSO and cross-service authentication.

During the years of its existence, Postgres Pro piled up a pool of problems when query execution was inappropriately slow or a query was too expensive to be executed, so it was never executed. Almost always in our practice, this was due to the choice of a non-optimal query plan. In our story, we will talk about a very unconventional attempt to solve this problem by re-planning queries. We will tell you what it is, how it works, who will find it helpful and the prospects for using this feature.
