AI projects today often rely on high-dimensional vector embeddings—for example, from text, images, audio, or user behavior—that power semantic search, recommendation systems, and natural language processing pipelines. Traditionally, handling such vectors required dedicated vector databases, introducing complexity in data pipelines and system architecture.
This talk focuses on the benefits of using pgvector, a powerful PostgreSQL extension that enables native vector similarity search directly within the PostgreSQL cluster. By embedding AI capabilities into the same environment as your relational data, pgvector eliminates the need for ETL pipelines between systems, improves performance through locality, and maintains transactional integrity. We’ll cover real-world use cases, performance considerations, and how pgvector simplifies deploying AI features like semantic search, nearest neighbor queries, and hybrid filtering using structured + unstructured data. Ideal for data engineers, ML practitioners, and Postgres users looking to integrate AI functionality with minimal infrastructure overhead.

As Arm CPUs become increasingly prevalent in data centers and high-performance computing, optimizing core database operations for vector performance is critical. To enable PostgreSQL to take full advantage of modern Arm architectures, we contributed the first-ever integration of Scalable Vector Extensions (SVE) into PostgreSQL. This work delivers a portable, vector-length-agnostic SIMD backend that boosts performance across a wide range of SVE-enabled Arm CPUs.
Our initial patch introduced vectorized versions of critical routines and setting the foundation for broader SIMD acceleration in PostgreSQL. First contribution introduced SVE-accelerated pg_popcount, used in visibility map operations that are fundamental to ANALYZE and VACUUM commands. This change delivered up to 7x speedup for that function on SVE-enabled platforms. Our second contribution focuses on optimizing hex encoding/decoding for bytea data types using SVE, achieving up to 10x speedup for these routines. Together, these improvements contributed upto ~11% performance gain on few queries in the TPC benchmarks.
These kernels are written using Arm SVE intrinsics and designed to scale with vector lengths from 128 to 512 bits, enabling performance portability across CPUs like AWS Graviton, A64FX, NVIDIA Grace, and Fujitsu’s upcoming MONAKA Processor (SVE2, 256-bit).
This talk will detail the motivation, design, and implementation of SVE support in PostgreSQL, discuss upstream collaboration, and present early performance metrics. We’ll also explore how this vectorization effort aligns with PostgreSQL’s long-term goals for extensibility and multi-architecture performance optimization.

In this talk, I will share how PostgreSQL has improved its security features over the years—from version 10 all the way to version 17. I’ll explain changes in user management, roles, and privileges, especially the update in version 15 where users no longer get the default CREATE privilege in the public schema. I’ll also talk about column-level security introduced in version 15, with real-life examples like protecting healthcare data.
I’ll then highlight the better role management in version 17, which gives more control and flexibility through role inheritance.
The session will also cover authentication and encryption improvements:
SCRAM-SHA-256 authentication from version 10
LDAP updates in version 11
GSSAPI encryption from version 12
Stronger password policies from version 13
SSL improvements in version 14
Direct TLS handshake support in version 17
To wrap up, I’ll talk about the new incremental backup feature in version 17, which helps prevent attackers from rebuilding the database without full backup access.

You run a few queries in development everything looks fast. But once your app goes live, you notice strange things: slow queries, deadlocks, growing table sizes, and confusing inconsistencies. Even something as simple as SELECT COUNT(*) feels unexpectedly slow. What’s going on?
In most cases, the answer lies in how PostgreSQL handles concurrency through MVCC—Multi-Version Concurrency Control. It’s a powerful system that lets PostgreSQL support high-concurrency workloads without locking readers and writers but it also introduces complexity that can catch you off guard.
This talk will walk through how MVCC actually works under the hood: how row versions are managed, how visibility is decided, and how background processes like autovacuum come into play. We’ll connect these internals to real-world issues you’ve probably faced—and explain how to solve them.
By the end of the session, you’ll know how to:
* Diagnose and resolve common performance issues caused by MVCC behavior
* Make informed choices around isolation levels and long-running transactions
* Tune autovacuum and avoid table bloat in write-heavy workloads
* Write safer, more scalable queries in concurrent environments
Whether you’re a developer, DBA, or architect, this talk will help you stop guessing and start making informed decisions about how your PostgreSQL database behaves under load.

For DBAs accustomed to Oracle’s ecosystem, the ability to surgically rewind data with Flashback is the gold standard for granular recovery. While PostgreSQL’s Point-in-Time Recovery (PITR) is exceptionally powerful for recovering an entire cluster, it often feels like a sledgehammer when a scalpel is needed. How do we recover a single table that was accidentally dropped, or reverse a fat-fingered UPDATE that affected millions of rows, without restoring the entire database? This session dives deep into the techniques and internal mechanisms that allow us to emulate Oracle’s Flashback capabilities using native PostgreSQL features. We will move beyond theory and into practice, unraveling the transaction log to perform surgical data recovery operations. |

Everyone’s building AI Agents. But ask what they really are, and the answers get fuzzy.
Under the broader umbrella of “a system that perceives its surroundings, gathers information, and uses it to perform actions and complete tasks autonomously,” we’ve seen a shift from traditional rule-based agents to learning-based agents, and now to multi-agent architectures. But what do these types of agents actually mean? How do you decide which one fits your use case? How do you build multi-agent systems that solve real-world problems? And are they truly necessary, or can Machine Learning and Generative AI apps do the job?
Join this session to gain a solid foundational understanding of AI Agents and their relevance in today’s world. You’ll learn what each type of agent entails, supported by live demos and practical examples. We’ll explore the current landscape of AI Agents, dive into frameworks like LangGraph, LlamaIndex, and Semantic Kernel (with a detailed feature-by-feature comparison), and show how to integrate them with PostgreSQL. You’ll also get clarity on today’s evolving terminologies and standards – all through a comprehensive end-to-end demo!
Consider this your complete beginner’s guide to AI Agents.

A default PostgreSQL installation can be dangerously permissive. While DBAs are diligent about setting roles and policies and privileges, true database security extends far beyond GRANT. This talk dives into critical, often-overlooked configurations and attack vectors to harden your database. This is a practical, two-part guide for engineers and DBAs ready to move beyond basics.
The first part: “Bare Minimums”, is a hands-on exploration of hardening database server itself. We start with initdb, enforce encrypted connections using hostssl, prevent password leakage in logs and configure meaningful audit trails.
The second part, “When ‘Best’ isn’t enough” explores reality that a “perfectly configured” database is not always perfectly secure. It explores how application-level vulnerabilities like SQL injection or network-level attacks like ARP spoofing can bypass your security controls, potentially compromising your data.
You will leave this talk with a checklist of hardening techniques and a broader security mindset to defend PostgreSQL instances against threats.
