PGConf.Russia is a leading Russian PostgreSQL international conference, annually taking together more than 500 PostgreSQL professionals from Russia and other countries — core and software developers, DBAs and IT-managers. The 3-day program includes training workshops presented by leading PostgreSQL experts, more than 40 talks, panel discussions and a lightning talk session.
Thems
- PostgreSQL at the cutting edge of technology: big data, internet of things, blockchain
- New features in PostgreSQL and around: PostgreSQL ecosystem development

Nikolay Samokhvalov Nombox LLCShared_buffers = 25% – is it too much or not enough? Or it's the right value?
How can we ensure that this – pretty much outdated – recommendation suit well our needs?
It is time to start apply enterprise-level approach to tuning postgresql.conf. Not using various blind auto-tuners or advices from old articles and blog posts, but based on the following two aspects:
- comprehensive database experiments, conducted in automated fashion, repeated multiple times in conditions as close to production as possible, and
- deep understanding of DBMS and OS internals.
Using Nancy CLI (https://gitlab.com/postgres.ai/nancy) we will consider a concrete example: infamous shared_buffers, under various circumstances, in various projects. We will try to figure out, how to optimize this settings for given infrastructure, database, and workload.

Nikolay Ryzhikov Health Samurai
Марат Сурмашев Health SamuraiJSONB in PostgreSQL has interesting properties for design and development of business systems with heavy domain, helping to fight against complexity and variability. We will discuss the trade-offs of the JSONB approach. Using an open source project for Health IT - fhirbase we will:
- load synthetic medical data into PostgreSQL
- learn how to search and index this data (gin, jsquery, json-knife)
- use JSON aggregation to build complex queries (GraphQL)
- see how this data can be modified and validated
- discuss architecture consequences of JSONB usage
Technical requirements:
- docker
- docker-compose

Stepan Danilov RT LabsI would like to share my experience in optimization queries in PostgreSQL of RMIS (Regional Medical Information System).

Alexander Kukushkin Zalando SEYou just set up your first PostgreSQL cluster, created a database schema, loaded some data, did some fine tuning of configuration. Now you want to make your cluster highly available. Unfortunately, PostgreSQL doesn't offer built-in automatic failover, but luckily for us, there are plenty of external tools for that. As a next logical step you start choosing a tool, and... you already doing it wrong, because first you have to define SLA, RTO, and RPO. In this talk I am going to cover most of the common mistakes people do when setting up a highly available cluster.
