Álvaro Hernández OnGresKubernetes 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.

Ivan Panchenko PostgresProIn this tutorial, we will solve several programming problems using JSON functionality that extends SQL capabilities and virtually turns a relational database into an almost ready-to-use application server. :)
We will learn how to use aggregates, both standard and custom, as well as review possible benefits of JSON recursive structure. -

Александр Кварацхелия БАРС Груп
Александр Чирков Барс ГрупIn the report, we want to talk about the experience of migrating one large system from Oracle to PostgreSQL. The system itself was built on the PHP + Oracle stack; its distinguishing feature was that all business logic was implemented in PL / SQL code. In a DBMS, there are more than 3000 packages with 4-10 functions (procedures) in each. In PHP - more than 10,000 forms with inserts of anonymous blocks used to receive data, process and save results in Oracle.
To solve this extremely voluminous work, we took ANTLR4 (a powerful parser generator for reading, processing, executing, or translating structured text), PL/SQL grammar, and created an automatic converter that allows you to convert all objects in the schema and our system from Oracle to working code for PostgreSQL.
