Postgres has always had strong support for relational storage. However, there are many cases where relational storage is either inefficient or overly restrictive. This talk shows the many ways that Postgres has expanded to support non-relational storage, specifically the ability to store and index multiple values, even unrelated ones, in a single database field. Such storage allows for greater efficiency and access simplicity, and can also avoid the negatives of entity-attribute-value (eav) storage. The talk will cover many examples of multiple-value-per-field storage, including arrays, range types, geometry, full text search, xml, json, and records.

In May 2019 «Postgres Professional» launched the PostgreSQL Certification Program. Now you can not only get training in our courses, but also confirm your knowledge by passing an appropriate set of tests.

In this presentation, I will share the results of the first months of the program and answer the most frequently asked questions:

Where can I get information about the certification program?
PostgreSQL or Postgres Pro certification?
Certificates for PostgreSQL version 10. When will you upgrade to the current version?
Do I have to attend training centers?
Can I pass the test remotely? Not in Moscow?
Is it possible to take several tests at once in one day?
How to prepare for the test? Are there any examples of training questions?
During the test I got an incorrect question, what should I do?
How to find out exactly which questions the answers were not correct?
When can I retake after an unsuccessful attempt?
How to appeal the test results? 

Kubernetes is the new way of deploying software, programmatically, on almost any infrastructure (be it cloud or on-prem). But is a complex beast. How to get started? How to dive deeper? What are the specific best-practices and special hints for Postgres DBAs dealing with Kubernetes? Join this half-day tutorial to learn, practically, among other topics:

• How to quickly get started with Kubernetes
• Manage storage
• Manage services, networking and ingress/egress
• How to make Postgres cloud-native in Kubernetes
• Do a show-run of existing Postgres operators, including Zalando, CrunchyData and StackGres.

This tutorial is very practical. BYOL! (Bring Your Own Laptop). With Kubernetes installed! (check microk8s, minikube or k3s if you don’t have any installed.

At the master class, we will learn how to execute fast load tests of Postgres databases: optimizing database configurations, data structure, indexes, OS settings, etc. To do this, we will create a code, build the infrastructure for the test from it and will do the test. As a result, we get a flexible tool in the code to which you can attach any monitoring, and for which you don't have to pay a lot of money, because the environment is created in 7 minutes in an empty AWS account and destroyed after test
