Introducing pgvector for Heroku Postgres

Over the past few weeks, we worked on adding pgvector as an extension on Heroku Postgres. We're excited to release this feature, and based on the feedback on our public roadmap, many of you are too. We want to share a bit more about how you can use it and how it may be helpful to you.

All Standard-tier or higher databases running Postgres 15 now support the pgvector extension. You can get started by running CREATE EXTENSION vector; in a client session. Postgres 15 has been the default version on Heroku Postgres since March 2023. If you're on an older version and want to use pgvector, upgrade to Postgres 15.

Last month, Heroku announced the beta release of Router 2.0, the new Common Runtime router!

As part of our commitment to infrastructure modernization, Heroku is making upgrades to the Common Runtime routing layer. The beta release of Router 2.0 is an important step along this journey. We’re excited to give you an inside look at all we’ve been doing to get here.

In both the Common Runtime and Private Spaces, the Heroku router is responsible for serving requests to customers’ web dynos. In 2024, Router 2.0 will replace the existing Common Runtime router. We’re being transparent about this project so that you, our customers, are motivated to try out Router 2.0 now, while it’s in beta. As...


We’re pleased to introduce the pgvector extension on Heroku Postgres. In an era where large language models (LLMs) and AI applications are paramount, pgvector provides the essential capability for performing high-dimensional vector similarity searches. This allows Heroku Postgres to quickly find similar data points in complex data, which is great for applications like recommendation systems and prompt engineering for LLMs. As of today, pgvector is fully compatible with all Production-tier databases running Postgres 15 at no additional charge and you can get started with a simple CREATE EXTENSION vector; command in your client session. In this post, we look at how you can use pgvector and...

In May 2023, we announced our limited release of two new Heroku Private Spaces regions: India (Mumbai) and Canada (Montreal). This month, we’re announcing the full general availability of those two regions, along with new Heroku Private Spaces regions for the United Kingdom (London) and Singapore. This expansion enables customers to maintain greater control over where their data is stored and processed. These four new regions fully support Heroku Private Spaces, Heroku Shield Private Spaces, Heroku Postgres, Apache Kafka on Heroku, Heroku Data for Redis, Heroku Connect, and most Heroku Add-ons.

Private Spaces provide a dedicated virtual network environment for running Heroku...
