こんにちは。 アプリケーションサービス、DevOps担当の兼安です。 AWS re:Invent 2025でAmazon Aurora PostgreSQL(以降、Aurora PostgreSQLと書きます)の動的データマスキングが発表されました。 今回はこれを機会に、行レベルセキュリティ（Row-Level Sec…

Today, we are launching dynamic data masking feature for Amazon Aurora PostgreSQL-Compatible Edition. In this post we show how dynamic data masking can help you meet data privacy requirements. We discuss how this feature is implemented and demonstrate how it works with PostgreSQL role hierarchy.

A small follow up on my previous post on various Postgres scale-up avenues in my preferred order. The post received quite a bit of interest - meaning people at least still “wish” performant databases :) And - the ones who are willing to put in a bit of effort with...

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...

Background

Amazon RDS Multi-AZ deployments with two readable standbys (Amazon RDS Multi-AZ DB cluster) for PostgreSQL now supports typically 35 seconds or less of write downtime for minor version upgrades and system maintenance updates. By using patches for PgBouncer from AWS, you can further reduce this write downtime to typically one second or less. This greatly […]

PostgreSQL is a powerful open-source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance. AWS offers Amazon Relational Database Service (Amazon RDS) and Amazon Aurora as fully managed relational database services. Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-compatible edition makes […]

An Amazon Aurora PostgreSQL-Compatible Edition cluster consists of a primary/writer node and up to 15 reader nodes in a Region. You may offload read-only workloads to reader nodes to scale-out reads. Long-running queries on reader nodes that are accessing tables with high transactional activities on the primary node can cause conflicts, and lead to undesirable […]

Amazon Relational Database Service (Amazon RDS) for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition version 9.6 end of life is approaching. If you’re currently running PostgreSQL 9.6, you must upgrade your databases or AWS will automatically upgrade your RDS for PostgreSQL databases starting January 18, 2022, and Aurora PostgreSQL databases starting January 31, 2022. Unlike […]

With the second gen of Graviton2 instances announced, we decided to take a look at the price/performance from the standpoint of running PostgreSQL.

Keeping your database version up to date provides benefits like improved performance and security, access to new features, fixes to known issues, compliance with regulatory requirements, and more. However, there is also a risk of some queries experiencing performance regression following a database upgrade. This risk is higher with major version upgrades because they can […]

“The greatest force in legacy databases is inertia,” a widely regarded industry analyst once told me. Not superior functionality. Not better performance. Not lower cost. None of the above. Just inertia. Developers might say they prefer to run PostgreSQL to proprietary alternatives (and they do), but enterprises have spent years building data models in Microsoft […]

Heroku PostgreSQL addon is excellent for a quick start setup of a new project. Once your web app matures, then migrating to an alternative database engine like Amazon RDS should be considered. In this blog post, I'll describe the benefits and drawbacks of using AWS RDS instead of the default Heroku addon. I'll also compare the pricing, available features, performance characteristics and explain why projects that care about EU GDRP compliance should avoid using the Heroku database.

January 2024: This post was reviewed and updated for accuracy. PostgreSQL is one of the most popular open-source relational database systems. The product of more than 30 years of development work, PostgreSQL has proven to be a highly reliable and robust database that can handle a large number of complicated data workloads. PostgreSQL is considered […]

We launched RDS PostgreSQL at AWS re:Invent in November of 2013 in order to bring the benefits of a managed database service to the PostgreSQL community. Customers of all sizes are bringing their mission-critical PostgreSQL workloads to RDS at a rapid clip. Here is a small sample of the applications that have been launched on […]
