Hello Azure Community,

November was an exciting month for PostgreSQL on Azure, packed with announcements at Microsoft Ignite 2025. In this recap, we’ll walk you through the highlights from features recaps to deep-dive sessions so you can catch up on everything you might have missed.

If you couldn’t join us live, here are some of the key sessions now available on demand:

• Modern data modern apps: Innovation with Microsoft Databases


• AI-assisted migration: The path to powerful performance on PostgreSQL


• Azure HorizonDB: Deep Dive into a New Enterprise-Scale PostgreSQL


• The blueprint for intelligent AI agents backed by PostgreSQL


• Nasdaq Boardvantage: AI-driven governance on PostgreSQL and Microsoft Foundry

We also introduced major updates, including Azure HorizonDB preview with AI capabilities and new features for Azure Database for PostgreSQL that make migrations faster, deployments smarter, and performance more predictable. The blog is organized into the following sections:

1. Azure HorizonDB (Preview)


2. Azure Database for PostgreSQL feature announcements


3. Azure HorizonDB: AI features & developer tools

Azure HorizonDB (Preview)

If it’s not obvious, the introduction of Azure HorizonDB is a big deal. This brand-new, fully managed PostgreSQL service is built for mission-critical workloads and modern AI applications, bringing cloud-native scale, ultra-low latency, and deep Azure integration in one powerful offering. Here are some of the features that we offer with Azure HorizonDB: 

• Scale-out compute architecture supporting up to 3,072 vCores across primary and replica nodes.


• Auto-scaling shared storage that handles databases up to 128 TB, while achieving sub-millisecond multi-zone commit latencies.


• Breakthrough throughput up to 3× higher than open-source PostgreSQL for transactional workloads, powered by our storage innovations.

Learn more about Azure HorizonDB in our detailed blog.

Azure Database for PostgreSQL feature announcements

We introduced a wave of new capabilities focusing on performance, analytics, security and AI-assisted migration for Azure Database for PostgreSQL. Among the key general availability announcements were PostgreSQL 18, Fabric mirroring, Elastic clusters, and support for Parquet in the azure_storage extension.

We also unveiled several exciting preview features, including Intel and AMD v6-series SKUs, the pg_duckdb extension, and enhanced tooling for Oracle-to-PostgreSQL migrations.

All these updates are captured in our blog post explore the full list and learn more.

Azure HorizonDB: AI features & developer tools

Azure HorizonDB isn’t just built for enterprise-scale workloads it’s also designed to power next-generation AI applications. At Ignite, we introduced advanced AI capabilities including DiskANN with Advanced Filtering, built-in AI model management, and Microsoft Foundry integration.

• DiskANN Advanced Filtering reduces query latency by up to 3×, depending on filter complexity.


• AI Model Management enables developers to set up semantic operators directly within the PostgreSQL environment, simplifying AI workflows.


• Microsoft Foundry Integration adds a PostgreSQL connector, allowing Foundry agents to interact with HorizonDB securely using natural language instead of SQL.

General Availability of PostgreSQL extension for VS Code

We announced the general availability of the PostgreSQL extension for VS Code, making development faster and more intuitive. The PostgreSQL extension for VS code has now over 300K downloads from the Visual Studio Marketplace! This extension makes it easier for developers to seamlessly interact with any PostgreSQL databases.
