File: AmazonRDS/latest/PostgreSQLReleaseNotes/postgresql-versions.md

Summary

Added documentation for PostgreSQL versions 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 on Amazon RDS, including parameter updates, new extensions (pgcollection, roaringbitmap), extension version updates (pgaudit, pg_tle, etc.), and removal of some extensions for v18

Security assessment

Updates include security-adjacent parameters like log_connections (improved logging granularity) and security-focused extensions like pgaudit. However, no specific vulnerabilities or security patches are explicitly mentioned. The pg_tle updates relate to Trusted Language Extensions security framework, qualifying as security documentation additions.

+
+PostgreSQL version 17.7 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the [PostgreSQL 17.7 release](https://www.postgresql.org/docs/release/17.7/).
+
+**General enhancements**

Collections maintain entries in creation order and can hold an unlimited number of elements constrained only by available database memory, with a maximum persisted size of 1GB when stored as a table column..
