When it comes to performing postgres upgrades between major versions the command line utility pg_upgrade is the most popular method used today. But as with all things wonderful, there are caveats. One of the more critical issues is what to do when there's a failure. The purpose of this talk is to present those little covered "tricks" of the trade that allows one to improve and enhance the upgrade experience.
We'll start out by reviewing its basic mode operation. We'll then learn what makes it so darn fast when upgrading multi-terabyte datacluster in a matter of minutes. Finally, you will be introduced to those feared failures and how to deal with them with confidence and certainty.
Herein is a summary of the topics in this talk:
- How pg_upgrade works: the big picture
- About pgupgrade (comand line invocation)
- arguments and options
- The steps performing an upgrade
- About the replication ROLE
- with replication
- with login
- Upgrade options: COPY vs Hard Link
- Post-upgrade
- about performance
- aboutanalyze
- repack
- reindexing
- When something goes wrong at the point of no return (or is it?)
- Upgrading the REPLICA
- default method: pg_basebackup
- the cool method:
- - leveraging rsync
caveat; about vacuum wraparound

In Zabbix Server 5.0.1 the PostgreSQL monitoring plugin has become available for Zabbix Agent 2. It was developed by Postgres Professional in collaboration with Zabbix. In the presentation, we will talk about how the plugin works, discuss some options for its configuration, as well as how to add custom metrics to it.

MobilityDB is a moving object database extension to PostgreSQL and PostGIS. It has types and functions for storing an querying geospatial trajectories, as first class citizens. The main type is called tgeompoint (temporal geometry point). It represents a complete movement track of a geometry point, such as a car, a bird, or a person. The function speed(tgeompoint) computes the time varying speed of the object, as a tfloat (temporal float). Similar to these examples, MobilityDB has 6 temporal types, and over 300 functions. As such, it is a function-rich platform for Mobility Data Management.
In this tutorial you will:
- learn about moving object databases
- write MobilityDB SQL queries and explore a database of geospatial trajectories
- walk through the different type, indexes, and functions of MobilityDB.
