This session dives into how to install, configure and use osm2pgsql on Linux to load OpenStreetMap data into PostGIS.  Loading the data into PostGIS is the first step required to begin consuming and leveraging OpenStreetMap data.  Where to download OSM data, best practices, helpful tricks and common pitfalls are all covered.

presented by Ryan Lambert

This session introduces the tools, concepts and basic queries needed for working with spatial data stored in PostGIS.  Building on the prior session, this session illustrates how to query and visualize OpenStreetMap data loaded to PostGIS.  Tools discussed in this session include GUI software as well as on-line resources for learning more about OpenStreetMap's Key/Value data structure.  

presented by Ryan Lambert

This session is a deep dive into complex spatial queries and performance tuning with PostGIS.  Common performance headaches are explored with a variety of approaches to remedy.  GIST indexes, proper data modeling, and materialized views are demonstrated.

presented by Joshua D. Drake and Erez Alsheich

Replicating live data (thousands of events per second) from Oracle to Postgres doesn’t have to be difficult. But the latency and complexity of traditional solutions, such as ETL, legacy CDC and homegrown scripts, have proven to be costly and inefficient. When you are replicating live data from one data platform to another, the process should be simple, inexpensive and as near real time as poss...

YugabyteDB is an open-source, cloud-native, high-performance database that belongs in the emerging distributed SQL category. Its storage layer uses a “shared nothing” architecture inspired by Google Spanner that brings linear write scalability, low read latency, and intrinsic fault tolerance. And, uniquely in its category, its query layer is implemented by using the “upper half” of the PostgreS...

Indexes are a basic feature of relational databases, and PostgreSQL offers a rich collection of options to developers and designers. To take advantage of these fully, users need to understand the basic concept of indexes, to be able to compare the different index types and how they apply to different application scenarios. Only then can you make an informed decision about your database index...

New monetization models such as open core have presented questions for IT professionals. Do we stick with the freedom and agility of community releases, or do we pay for the enterprise counterparts? Explore patterns in Enterprise Edition add-ons, look at some concrete examples such as Confluent vs. Kafka, and be better prepared to decide where you spend your open source license dollars.

presented by Tong Zhang

This talk will present a solution that allows Postgres users to achieve significant data storage savings through compression at zero CPU/performance cost. The key is to deploy Postgres on new compression-capable solid-state drives (SSDs), which is developed following the current industry trend of empowering data storage devices with additional computing capability. This proposed talk will discu...

Optimizing a PostgreSQL database may be a challenge if some of the important parameters are ignored. And a bigger challenge may be the understanding of the algorithm behind setting those parameters correctly. In my experience with PostgreSQL Consulting for more than a decade, I have seen a bigger list of parameters that are wrongly set or ignored. This talk details a list of important PostgreSQ...

Sharding is how most of us scale Postgres. It works, however, it is not without its challenges. What key should we shard on? How big will my shards need to be? How will sharding affect performance? What application-level mods will need to happen? What happens if we need to re-shard the database?

Automating the sharding process seems right. We should be able to define a shard and let the db t...

Right execution plans can deliver maximum performance and throughput from your PostgreSQL database. It is important to understand all factors which affect the execution plan which includes costing, datatypes, indexing, filter and join conditions, pruning, runtime exclusions, etc. Poor understanding of the planner leads to suboptimal performance. There are substantial improvements in new vers...

Developers love working with JSON. Document stores like MongoDB have proved to be very popular. Both MongoDB and PostgreSQL have built-in support for the 'JSON' data type. Understand the pros and cons of working with JSON in both of these databases - when should you use MongoDB vs. PostgreSQL? If you are already comfortable with PostgresSQL, should you continue to use it for your JSON data? In ...

Depending on the project, debugging can take 50 to 90% of development time. But it usually gets less than 10% of the press. PostgreSQL has great tools for debugging, but they are most effective when deployed as part of an overall strategy.

We will look at strategies for debugging PostgreSQL: how to find bugs, how to fix them, and how to keep them from happening in the first place.

We’ll l...

IT Administrators need to keep an eye on Availability, Performance, and Storage of mission- critical environments. There are many things to consider as you develop a Monitoring and Diagnostics strategy. Items to consider include:

• All-in-one or Specialized?
• Build vs Buy
• Real-time diagnostics vs 24x7 monitoring
• Architecture: Agents? Overhead? Flexibility?
• Configuration: On-...

When the data you need is located in multiple servers you're faced with time-consuming and difficult choices to query it. The easy button for solving this is to use open-source abstraction layers such as Starburst Presto which just needs the connection string for each of the servers to create a single federated point of access for you. The Presto abstraction layer:

With PostgreSQL recently being voted the second-most loved database, and Rust being voted the most loved programming language, it's about time we be able to integrate the two.

PostgreSQL's extension system is second-to-none, however its main barriers are the need for a background in C and an understanding of Postgres' source code.

"pgx" aims to mitigate these barriers by providing a P...

In responding to an RFP to optimize and improve street sweeping routes for a small city in California, we developed a solver based on Google's Operations Research Tools. While the guts of the solver uses OR-Tools, virtually everything else about the project is made possible by PostgreSQL, PostGIS, and pgRouting.

In this presentation, I talk about the various ways PostgreSQL and friends made ...
