Typical errors in application software working on PostgreSQL

Software applications working on PostgreSQL is a very typical case in my practice. Some of them manage to work well, some of them do not. In the talk I will focus on errors and problems of the last ones.

How and what we'd choose between patroni, stolon, repmgr for out HA Postgres

While doing development of one of our project we were asked to build HA database using Postgres, geographically distributed.
First our choice was obvious, we started to work with big 3 cloud providers, but soon it was quite understand that everything costs big enough for us. Also there were a bunch of incompatibilities with unsupported extensions as well as londiste replication we were heavily used.
I will talk about why we chose patroni, what types of problem we faced with and patroni's special features can dramatically simplify deploy and everyday usage.

Using JSONB

JSONB 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
