Your organization may have many reasons to move a cloud service from one provider to another. Maybe you’ve found a better performance-versus-cost balance elsewhere. Maybe you’re trying to avoid vendor lock-in. Whatever your reasons, the convenience and general interoperability of cloud services today put you in the driver's seat. You get to piece together the tech stack and the cloud provider(s) that best align with your business.

This includes where you turn for your PostgreSQL database.

If you’re considering migrating your Postgres database to a different cloud provider, such as Heroku, the process might seem daunting. You’re concerned about the risk of data loss or the impact of...

We’re thrilled to launch our new Heroku Postgres Essential database plans. These plans have pgvector support, no row count limits, and come with a 32 GB option. We deliver exceptional transactional query performance with Amazon Aurora as the backing infrastructure. One of our beta customers said:

“The difference was noticeable right from the start. Heroku Postgres running on Aurora delivered a boost in speed, allowing us to query and process our data faster.”

Our Heroku Postgres Essential plans are the quickest, easiest, and most economical way to integrate a SQL database with your Heroku application. You can use these fully managed databases for a wide range of applications, such as...

Update: On closer inspection, the lock type was not on the table, but on a tuple. For more information on this locking mechanism see the internal Postgresql tuple locking documentation. Postgres does not have lock promotion as suggested in the debugging section of this post.

I maintain an internal-facing service at Heroku that does metadata processing. It's not real-time, so there's plenty of slack for when things go wrong. Recently I discovered a Postgres performance issue that bogged down the system to the point where no jobs were being executed at all. After hours of debugging, I found that an UPDATE on a single row on a single table was causing the entire table to lock,...

Today, we’re thrilled to announce four new trusted data integrations that allow data to flow seamlessly and securely between Heroku and external resources in public clouds and private data centers:

• Heroku Postgres via mutual TLS
• Heroku Postgres via PrivateLink
• Apache Kafka on Heroku via PrivateLink
• Heroku Key-Value Store via PrivateLink

These integrations expand Heroku's security and trust boundary to cover the connections to external resources and the data that passes through them. They enable true multi-cloud app and data architectures and keep developers focused on delivering value versus managing infrastructure. Data is the driving force in modern app development, and these...

There are many reasons to choose Heroku Data services, but keeping the services you use secure and up-to-date rank near the top. This foundation of trust is the most important commitment we make to our customers, and frequent and timely maintenances are one way we deliver on this promise.

We do everything we can to minimize downtime, which is typically between 10 – 60 seconds per maintenance. There are ways for you to minimize disruption too (see the tips and tricks below). The rest of the post explains how we think about Heroku Data maintenances, how we perform them, and when we perform them.
