Index types supported in Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL (B-tree)
In this series of posts, we discuss index types supported in Amazon Aurora PostgreSQL-Compatible edition and Amazon Relational Database Service (Amazon RDS) for PostgreSQL and their use cases. In this post, we discuss the native B-tree index and its variations.
Key considerations when choosing a database for your generative AI applications
In this post, we explore the key factors to consider when selecting a database for your generative AI applications. We focus on high-level considerations and service characteristics that are relevant to fully managed databases with vector search capabilities currently available on AWS. We examine how these databases differ in terms of their behavior and performance, and provide guidance on how to make an informed decision based on your specific requirements.
Synopsis of several compelling features in PostgreSQL 16
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.
AWS DMS homogeneous data migration from PostgreSQL to Amazon Aurora PostgreSQL
With AWS DMS homogeneous migration, you can migrate data from your source database to an equivalent engine on AWS using native database tools. In this post, we show you an example of a complete homogeneous migration process and provide troubleshooting steps for migrating from PostgreSQL to Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL.
Benchmark Amazon RDS for PostgreSQL Single-AZ DB instance, Multi-AZ DB instance, and Multi-AZ DB Cluster deployments
In this post, we present a qualitative performance comparison between RDS for PostgreSQL Single-AZ DB instance, Multi-AZ DB instance, and Amazon RDS Multi-AZ DB Cluster deployments.
Automate interval partitioning maintenance and monitoring in Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL – Part 2
In Part 1 of this series, we demonstrated how to configure interval partitioning in an Amazon Aurora PostgreSQL-Compatible Edition database using PostgreSQL extensions such as pg_partman and pg_cron. The monitoring job was external to the database, thereby allowing a centralized monitoring solution. In this post, we demonstrate how you can monitor and send alerts using […]
Perform maintenance tasks and schema modifications in Amazon RDS for PostgreSQL with minimal downtime using Blue Green deployment
Important Since November 22nd, 2024, Amazon RDS Blue/Green deployments for RDS for PostgreSQL minor version upgrades use physical replication slots which do not support table modifications on the green instance. This means the contents of this post won’t work with RDS for PostgreSQL minor version upgrades. The content is still accurate for RDS for PostgreSQL […]
Managing object dependencies in PostgreSQL: Removing dependent objects (Part2)
In PostgreSQL, object binding (or dependencies) encompasses the connections existing among various database elements. These interdependencies hold significant importance when it comes to the management and modification of objects within the database. They ensure that adjustments made to one object don’t inadvertently disrupt other dependent objects. This series is divided into two posts. In the […]
Managing object dependencies in PostgreSQL – Overview and helpful inspection queries (Part 1)
In PostgreSQL, object binding (or dependencies) encompasses the relationships existing among various database elements. These interdependencies hold significant importance when it comes to the management and modification of objects within the database. They ensure that adjustments made to one object don’t inadvertently disrupt other dependent objects. For instance, when a view relies on a table, […]
Enhance PostgreSQL database security using hooks with Trusted Language Extensions
PostgreSQL has the ability to authenticate user names and passwords using native credentials, though it lacks the ability to enforce specific password complexity and other advanced authentication policies without external identity services like LDAP or Kerberos. Trusted Language Extensions (TLE) for PostgreSQL (pg_tle), an open-source development kit used to build and package extensions, lets you […]
