Amazon RDS for PostgreSQL supports client authentication hook for Trusted Language Extensions

[Trusted Language Extensions for PostgreSQL](https://aws.amazon.com/about-aws/whats-new/2022/11/trusted-language-extensions-postgresql-amazon-aurora-rds/) (pg\_tle) now supports client authentication hook that lets you run additional checks over the existing authentication process, allowing you to enhance the security posture of your databases. A hook is an internal callback mechanism available to developers for extending PostgreSQL's core functionality. By using hooks, developers can implement their own functions or procedures for use during various database operations. This release also includes additional updates for pg\_tle such as password checks across all the databases on a RDS DB instance and enhanced custom datatype to support [TOAST](https://www.postgresql.org/docs/current/storage-toast.html). Support for client authentication hook, password checks, and enhanced custom datatype is available on database instances in Amazon RDS running PostgreSQL 16.2-R2 and higher, 15.6-R2 and higher, 14.11-R2 and higher, and 13.14-R2 and higher in all applicable AWS Regions. To learn more about using pg\_tle, see our [documentation](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL%5Ftrusted%5Flanguage%5Fextension.html). Amazon RDS for PostgreSQL makes it simple to set up, operate, and scale PostgreSQL deployments in the cloud.
