Supported Minor Versions on Amazon RDS

Amazon RDS for PostgreSQL currently supports the following minor versions:

  • PostgreSQL 16.2
  • PostgreSQL 15.6
  • PostgreSQL 14.11
  • PostgreSQL 13.14
  • PostgreSQL 12.18

Each of these minor versions has its own set of features, improvements, and bug fixes. It is important to review the release notes for each version to determine which one best meets your needs.

Performance Improvements with pgvector 0.6.0

In addition to the minor version updates, Amazon RDS for PostgreSQL now supports pgvector 0.6.0. This release introduces performance improvements for building Hierarchical Navigable Small Worlds (HNSW) indexes, including enhancements for parallelism and in-memory builds.

Parallelism

pgvector 0.6.0 enhances the parallel processing capabilities of PostgreSQL, allowing for more efficient execution of queries that can be split into multiple tasks. This can help speed up query performance, particularly for complex analytical workloads.

In-Memory Builds

With in-memory builds, pgvector 0.6.0 enables faster index creation by utilizing memory resources instead of disk storage. This can lead to significant performance gains for index-intensive operations, such as sorting and searching large datasets.

Best Practices for Upgrading Minor Versions

Before upgrading to a new minor version of PostgreSQL on Amazon RDS, it is important to follow best practices to ensure a smooth transition:

Backup Your Database

Before performing any upgrades, always make a complete backup of your database to safeguard against data loss in case of any unforeseen issues during the upgrade process.

Test in a Staging Environment

Prior to upgrading your production database, test the new minor version in a staging environment to identify any potential compatibility issues or performance concerns.

Monitor Performance Metrics

After upgrading to a new minor version, closely monitor performance metrics to ensure that the database is functioning as expected. Keep an eye on key indicators such as query response times, CPU usage, and memory consumption.

Rollback Plan

In the event that the upgrade does not go as planned, have a rollback plan in place to revert to the previous version quickly and effectively.
