New submission: Monitoring PgVector RAG Agents Applications
by HOW2025 May 27, 2025

May 27, 2025

Jayita Bhattacharyya has submitted a new session! Monitoring PgVector RAG Agents Applications pgvector within Retrieval-Augmented Generation (RAG) agents. As pgvector integrates vector similarity search capabilities into PostgreSQL, ensuring optimal performance and reliability in RAG workflows is crucial. Proposals should address:Performance Monitoring: Techniques for tracking and analyzing pgvector query performance, including latency, throughput, and resource utilization. Utilizing PostgreSQL's built-in tools like EXPLAIN and ANALYZE can be beneficial. Error Detection and Debugging: Methods to identify and resolve errors or anomalies in pgvector operations within RAG applications. Implementing observability tools can aid in monitoring and debugging complex RAG-based systems. Scalability and Resource Management: Strategies to monitor and manage resource allocation, ensuring efficient scaling of pgvector in RAG contexts. Scaling pgvector can be achieved by increasing memory, CPU, and storage on a single instance, or by using replicas and sharding techniques. Integration with Observability Tools: Approaches to incorporate existing observability platforms for comprehensive monitoring of pgvector within RAG pipelines. Tools like New Relic offer observability quickstarts for pgvector, providing dashboards and alerts to monitor key performance metrics.

New submission: What is Patroni, really?
by HOW2025 May 25, 2025

May 25, 2025

Alexander Kukushkin has submitted a new session! What is Patroni, really? Patroni is widely recognized as a high-availability solution for PostgreSQL—but what really makes it tick? In this talk, we’ll explore its architecture, core principles, and the clever mechanisms that keep it resilient in production. We’ll go beyond the documentation to uncover the design decisions—both brilliant and painful—that shaped Patroni into what it is today. We’ll also touch on the practical challenges that come with deploying Patroni in real-world environments: choosing and managing distributed configuration systems like Etcd or Consul, handling backups and point-in-time recovery, managing PostgreSQL configuration, and integrating tools like pgbouncer. These are the kinds of questions that regularly surface in the community and define what it means to run Patroni in production.

New submission: Switching to Open: Why PostgreSQL and IvorySQL Make Business Sense
by HOW2025 May 23, 2025

May 23, 2025

Andrea Cucciniello has submitted a new session! Switching to Open: Why PostgreSQL and IvorySQL Make Business Sense This non-technical talk explores the business and operational case for adopting open-source databases, with a focus on PostgreSQL and IvorySQL.I’ll share how we at Data Bene help organisations transition from proprietary systems, and how open-source adoption fits into a broader strategic and commercial framework. IvorySQL plays a key role in our customer journey model, particularly for Oracle compatibility.

New submission: Stats roll, baby, stats roll.
by HOW2025 May 22, 2025

May 22, 2025

Cédric Villemain has submitted a new session! Stats roll, baby, stats roll. PostgreSQL 18 will offer extension developers support for defining new statistics, using the native PostgreSQL Cumulative Statistics. We're talking about stats similar to what's in `pg_stat*` views and functions, and how you will be able to define your own views and functions in the future. Using the PACS (PostgreSQL Advanced Cumulative Statistics) extension, we will explore what is offered by PostgreSQL as well as how to define your own new kind of statistics. We will also see how to benefit from the C and SQL API provided by PACS to setup your own gauge, counters, buckets and histogram.

New submission: Resource Control Admission - I have a date with my PSI
by HOW2025 May 22, 2025

May 22, 2025

Cédric Villemain has submitted a new session! Resource Control Admission - I have a date with my PSI Pressure Stall Information (PSI) has been present in Linux for numerous years, but even so, it's not well known in the world of PostgreSQL. In this talk, we'll introduce PSI along with what it brings, how it works, and where it is used today. Then, we will use the `pg_psi` extension to start "playing" with PSI and react to system events. To do this, we will define system triggers so we're notified when the server is slowing down. This gives us the chance to adjust the workload before it's too late, or give more resources to background tasks like auto-vacuum when it's possible.

New submission: Spat: Hijacking Shared Memory for a Redis-Like Experience in PostgreSQL
by HOW2025 May 22, 2025

May 22, 2025

Florents Tselai has submitted a new session! Spat: Hijacking Shared Memory for a Redis-Like Experience in PostgreSQL Databases traditionally use shared memory as a transient workspace for query execution, caching, and transaction management, hidden from direct user control. But what if we could repurpose it for user-facing, high-performance data structures and general caching? In this session, I’ll explore PostgreSQL’s shared memory APIs available to extension developers, including recent features like the DSM Registry. I’ll introduce Spat, a Redis-like in-memory data structure server embedded within PostgreSQL, where data is stored entirely in shared memory. Spat provides an extended key-value model in which keys are strings, and values can be strings, lists, sets, or hashes. This offers a fast, lightweight alternative for ephemeral storage inside PostgreSQL. This talk will explore the technical challenges and opportunities of using shared memory beyond its traditional scope, providing ideas for anyone interested in extending PostgreSQL.

New submission: Doing More with JSONPath: Turning a Query Language into a Transformation Engine
by HOW2025 May 22, 2025

May 22, 2025

Florents Tselai has submitted a new session! Doing More with JSONPath: Turning a Query Language into a Transformation Engine PostgreSQL’s JSONPath engine is often seen as just a filtering tool — but its real potential lies much deeper. In this talk, we’ll explore how the JSONPath infrastructure can serve as a foundation for building powerful, domain-specific languages (DSLs) within Postgres. Drawing on my recent work to extend JSONPath with richer text processing functions like lower(), replace(), we’ll demonstrate how these additions evolve JSONPath from a query language into a lightweight transformation engine. You’ll learn:• How JSONPath is implemented in PostgreSQL and why it’s extensible• The design rationale behind adding composable text functions to the language• How these functions open the door to expressive, pipeline-style data transformations• Why JSONPath’s AST and evaluation model make it a great blueprint for custom DSLs If you’re interested in Postgres internals, building smarter queries, or embedding logic closer to the data — this is your invitation to rethink what JSONPath can do.
