The Future of Postgres in a Changing World
Open source software programs, including PostgreSQL, first arose to prominence in the 1990s. This was a product in part of geopolitical and economic changes of the time, particularly the role that globalization played in the development of open source software. Today the world is changing again and we are seeing an effort to disconnect economies. What does this mean for the future of open source software in general and PostgreSQL in particular?
Recently we have seen a lot of warning signs from the US including the failed RESTRICT Act, the purges of certain Russian Linux kernel maintainers, and more, and there are reasons to think that open source software may be in the crosshairs of some governments from a geopolitical perspective. What does this mean for the future of PostgreSQL? How should people evaluate open source projects in terms of geopolitical risks? And what can we do to help ensure the community is geopolitically resilient?

Building Resilient PostgreSQL Systems: HA and Load Balancing Techniques
In this workshop we will be setting up a High Availability (HA) and load balancing environment for PostgreSQL which can be quite beneficial for ensuring your database remains operational and performs well, even under heavy load or during failures. Here are some options you can consider for your workshop: High Availability (HA) Options Streaming Replication: Synchronous Replication: Ensures no data loss by waiting for the standby server to confirm the transaction before committing. Asynchronous Replication: Faster but may result in some data loss if the primary server fails before the standby catches up. Logical Replication: Allows replication of specific tables or databases, providing more flexibility. Failover Solutions: Patroni: A popular tool for managing PostgreSQL HA, which automates failover and recovery. PgBouncer: Lightweight connection pooler that can help manage database connections efficiently. Load Balancing Options Pgpool-II: A middleware that provides connection pooling, load balancing, and replication management. Supports both read and write load balancing. HAProxy: A robust load balancer that can distribute read-only queries across multiple replicas. Citus: A PostgreSQL extension that transforms your database into a distributed system, enabling horizontal scaling and load balancing. Example Setup for Workshop Primary and Standby Servers: Configure streaming replication between primary and standby servers. Use synchronous replication for critical data to ensure no data loss. Load Balancer: Set up Pgpool-II or HAProxy to distribute read queries across multiple replicas. Ensure write queries are directed to the primary server. Monitoring and Failover: Implement Patroni for automated failover and recovery. Use monitoring tools like Prometheus and Grafana to keep track of your database health. Technical Requirements: Laptop with 8 GB RAM, 2 - 3 Linux VM's with 50 GB storage of each VM. Target Audience : Students, IT Professionals (Beginners, Intermediate, Advanced)

Why can’t we continue a transaction after an error?
Subtitle: A journey into the subterranean world of subtransactions In this workshop we are going to cover rather wide range of features related under the hood to the subtransaction mechanics. Among them: snapshot isolation and multiversion concurrency control, transaction-level and statement-level rollback, rollback to savepoint, subtransactions vs autonomous transactions, PL/pgSQL exception handling and its overhead. The objective is to lay a foundation that allows us to reason about the root causes of seemingly unrelated outcomes. This workshop is intended for mid-level developers and DBAs who have some PostgreSQL experience and want to gain deeper knowledge of inner workings of the server. People with previous Oracle experience will further benefit from brief comparison of these two systems. --- 2 hours workshop. Together with Pavel Luzanov.

Extensions in PostgreSQL, and how to develop one
Overview The workshop is intended to provide an overview of the PostgreSQL Extensions, along with a hands-on session on enabling users to develop a custom extension by themselves. Extensions on PostgreSQL are there to enhance the functionality of the Database System. It adds extra functionality to your database by modifying and enhancing the execution of certain processes. Most of the developers are unaware of the extensions in PostgreSQL, hence they build their own modules in programming languages instead of leveraging the benefit from built-in extensions. This adds upon extra time and effort onto the development phase, which affects the resource allocation of the whole project. With the help of this workshop, participants should be able to get themselves familiar with extensions in PostgreSQL and be able to build one for themselves. The workshop shall be conducted in two phases: 1. Introduction to PostgreSQL built-in extensions 2. Creating a custom extension The main intention of the first phase is to get participants familiar with some popular built-in extensions of postgres contrib, such as pgcrypto, plpgsql, pg_stat_statements, pg_trgm. This will help participants understand how an extension adds upon the functionality provided by the database system and sometimes eases up their work burden through readily available functions. On to the second phase, we’ll try hands-on exercise for developing a custom extension for PostgreSQL. This will include creating a control file for the extension in C, writing plpgsql functions to achieve an output and finally compiling the extension using gcc. Upon completion of the workshop, participants will have a clear understanding on the usages of PostgreSQL extensions and why one should develop it, if need be. Speaker’s Bio My name is Swastik Gurung, currently working as a Data Operations Manager at Bajra Technologies Pvt. Ltd., having 8 years of Experience with PostgreSQL and MySQL. I have previously participated in PgConf Nepal 2018 and 2023, while delivering a workshop during PgConf 2018 titled “Acquiring government compliance for computerized billing using PostgreSQL”. Target Audience This session is intended for PostgreSQL Enthusiasts, Database Administrator and Developers. Technical Requirements Below are the list of technical requirements for the session: - Prior Knowledge of SQL and PostgreSQL, PostgreSQL (latest) setup in a local or dockerized environment. - Client tool for PostgreSQL (psql, PgAdmin, DBeaver) - Linux Operating System (preferably) - Some experience on Linux/Bash command - Internet connection on the PC - C compiler should be installed on a local machine, for building the extension file.

PostgreSQL Tools for Hunting Down and Fixing Non-Optimal Queries
Performance is a key quality of DBMS operation. But sometimes an attempt at optimization looks like detective work: it is necessary to identify queries for improvement and then transform them. In this report, we will learn what tools PostgreSQL has to find potential candidates for improvement: slow, blocking, unnecessary or error-containing queries. Why and how to read the EXPLAIN and EXPLAIN ANALYZE results, why the optimizer does not always choose the best execution method and how to fix this with proper configuration. We will consider open source extensions for researching and configuring queries. Based on the results of the report, we will compile a consistent list of possible actions for query optimization.

Addressing Scalability Challenges in PostgreSQL Sharding: Key Issues and Solutions
In the era of big data, the ability to scale databases efficiently is crucial for maintaining performance and reliability. PostgreSQL, a powerful open-source relational database management system, offers a variety of solutions to address scalability challenges. PostgreSQL sharding is an advanced method for achieving horizontal scalability by partitioning data across multiple servers. However, its implementation presents several technical challenges that must be addressed to ensure optimal performance and reliability. This abstract identifies key issues in PostgreSQL sharding, including: Uneven data distribution: Ensuring data is evenly distributed across shards to prevent hotspots and ensure balanced load. Performance degradation of cross-shard queries: Mitigating the latency and complexity associated with queries that span multiple shards. Data consistency in distributed transactions: Maintaining ACID properties across distributed transactions to ensure data integrity. Balanced data growth: Managing the even growth of data across shards to avoid imbalances. Shard health monitoring: Continuously monitoring the health and performance of each shard to detect and address issues promptly. This abstract also proposes solutions to these challenges, such as implementing effective sharding strategies, optimizing query performance, and employing robust monitoring tools.
