AWS AmazonRDS documentation change
Summary
Added multiple bug fixes and enhancements across Aurora PostgreSQL versions including: fixes for ANALYZE operations with large LOB data, correlated any transforms, optimization triggers, reader availability during catch-up, CPU overhead reduction for Encryption in Transit, storage connection loss handling, and ALTER FUNCTION failures.
Security assessment
The change adds documentation about reducing CPU overhead for 'Encryption in Transit' between database and storage layers, which is a security feature. No vulnerabilities or security incidents are explicitly mentioned in the fixes. Other changes address functional correctness and stability issues without security implications.
