In this post, we explore the new features in PostgreSQL 16 and discuss how they improve performance and query speed. This includes new replication features, including logical decoding on standbys and parallel application of logical replication, SQL/JSON functionality, new monitoring tools, such as the pg_stat_io system view, and security features.

It’s important to understand strategies for how to use pgvector with your Generative AI applications so you can find the optimal configurations. This can include the selection of your database instance family, how you ingest your data, and even the version of pgvector you’re using. We ran a series of tests to see how pgvector […]

In this post, we walk through an example for creating an active-active replication setup between two RDS for PostgreSQL instances. We also show how to monitor replication lag between instances, and review how to detect and resolve conflicts. Finally, we discuss strategies to design applications to work with pgactive.

Amazon Relational Database Service (Amazon RDS) for PostgreSQL now supports trusted PL/Rust, allowing developers to safely build high-performance database functions in the Rust programming language. PL/Rust is an open-source project that lets you write Rust code that runs directly inside a PostgreSQL database, and provides support for PostgreSQL features such as running queries, writing trigger […]

In this post, we explore how text collations work in PostgreSQL, the effect on PostgreSQL when the collation changes, and how to detect these changes. We also review how Amazon Relational Database Service (Amazon RDS) and Amazon Aurora can help you manage collations using an independent default collation library, and future work in PostgreSQL on […]

The Kubernetes container orchestration system provides numerous resources for managing applications in distributed environments. Many of these applications need a searchable storage system for their data that is secure, durable, and performant. Developers want to focus on continuously improving their apps rather than having to worry about the operational functions of their databases. They also […]
