Practical Postgres Replication
In this tutorial we will discuss Binary and Logical replication in a practitioner format. The topics that will be included are native Postgres replication technologies, configuring and managing them. We will also discuss performance and draw backs of various architectures (sync vs async etc...). At the end of this presentation the attendees will be able to configure a basic replication deployment with HOT Standby and well as have an understanding of other technologies such as Point in Time Recovery and cascading replication.

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.

Bitemporality: Tracking Reproducible Revisions in PostgreSQL Using RANGE Types
So you finally have your database model for your application and you fill it in with current data. How do you keep it up to date? While INSERT may still be transparent, UPDATE and DELETE will overwrite your previous data, so you won't be able to reproduce them. Cloning the whole huge content for each minor update is not an option. For rich and complex data about hundreds of thousands of power generators in Germany and worldwide, I built a model using range data types in recent PostgreSQL which allows me to insert, update and delete data while granting the full access to the whole state of the database at any historical moment. I'll present a very simplified version of the database so the audience will be immediately able to apply it for their cases. I'll also show a few tricks in Python and Psycopg2 that will allow a whole team to prepare, review, and deploy all revisions to this database without merge conflicts. And I'll give a few ideas on how to retrieve this data efficiently.

LTREE: extending the syntax
At the end of 2018, I've got a request to extend the syntax of the ltree contrib. I'm finalizing the patch and going to speak about:
- the current state of the extension,
- the extended syntax, and
- the process of development and testing the extension.

Tips and Tricks with Amazon RDS for PostgreSQL
Managed database services are gaining in popularity. In this session we look at how best to configure Amazon RDS for PostgreSQL and also look at common user operations of using RDS for PostgreSQL. We will also look beyond common user operations and into some specific optimizations related to upgrade, logical replication, performance, and reducing downtime.
