AWS AmazonRDS: Add new Aurora PostgreSQL engine versions to extension version tables

Service: AmazonRDS · 2026-09-30 · Documentation low

File: AmazonRDS/latest/AuroraPostgreSQLReleaseNotes/AuroraPostgreSQL.Extensions.md

Summary

Adds new engine version columns (18.6, 17.11, 16.15, 15.19, 14.24) and updates supported extension versions across the Aurora PostgreSQL extension support tables. Routine release-notes maintenance; no security-specific content.

Security assessment

The diff only adds new engine version columns and refreshes extension version numbers in support matrices. While some listed extensions (pgAudit, pgcrypto, sslinfo) are security-relevant, the change is purely a version-table update with no mention of a vulnerability, CVE, or security guidance, so it is not security-issue related.
