In this post, we walk you through performing schema changes and common maintenance tasks such as table and index reorganization, VACUUM FULL, and materialized view refreshes with minimal downtime using blue/green deployments for an Amazon Relational Database (Amazon RDS) for PostgreSQL database or an Amazon Aurora PostgreSQL-Compatible Edition cluster. Solution overview Amazon RDS blue/green deployment […]

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 […]

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, […]

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 […]

As we continue to innovate and add new features on behalf of our customers, you can now maintain and manage query plans in Amazon Aurora PostgreSQL-Compatible Edition. This feature enables you to identify the query plans contributing to the current database load and track the performance statistics of query plans over time. In this post, […]

Amazon Relational Database Service (Amazon RDS) supports several ways to authenticate database users, including password authentication, Amazon Identity and Access Management (IAM) database authentication, and Kerberos authentication. When working with MySQL, PostgreSQL, and Amazon Aurora database engines, you can authenticate to the database using IAM, which uses an authentication token instead of the password to […]

In this post, we show you how to replicate data between partitioned and non-partitioned tables using trigger functions in Amazon Aurora PostgreSQL-Compatible Edition. The solution also works with Amazon Relational Database Service (Amazon RDS) for PostgreSQL. Customers often decide to migrate partial applications and their associated database objects to AWS, which requires synchronizing data from […]

One critical aspect during the migration process from Oracle to PostgreSQL is identifying any semantic issues that may arise when translating Oracle-specific code to PostgreSQL. Although Oracle performs both semantic and syntax checks during code compilation, PostgreSQL focuses solely on syntax checks during code compilation, leaving room for potential semantic discrepancies in the converted code […]

In recent times, there has been a growing interest in using foundation models (FMs) to build generative AI applications. These models are trained on vast amounts of data and are capable of performing tasks that were previously thought to be the exclusive domain of humans, such as creating art and music. However, when it comes […]

Migrating from Oracle to PostgreSQL can involve several steps to ensure a smooth transition. A notable example is an Oracle collection, which is a feature that Oracle database developers commonly use. PostgreSQL does not directly support Oracle collections, and there currently isn’t an extension that adds this capability. There are several decisions you have to […]
