Backup for 1.5K clusters with pg_probackup
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.

Иван Чувашов ООО CalltouchSeveral 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.

Igor Kosenkov Postgres ProfessionalBuilding a GEO-Cluster
Everyone knows very well what a failover cluster PostgreSQL is and how such a cluster protects against failures within the same data center. However, recently, more and more enterprises have placed increased demands on their services, these requirements include disaster tolerance. We call such clusters a GEO-Cluster (KUK). In the report, I will talk about the varieties, principles and approaches to building GEO-Clusters PostgreSQL based on the Corosync/Pacemaker cluster software.

Tatiana Krupenya DBeaver CorpHow to speed up data load up to 10,000 times?
What can be more important in the data load process than speed? Data migration is one of the most requested features in DBeaver. So the performance issue was highly important for us, in regard to PostgreSQL, as well as Greenplum, Redshift and other Postgres-based databases. We are ready to share our tiny secrets about 10x, 100x, 1000x, and even 10,000x performance improvements for data imports without any magic.
