You can invoke Lambda functions directly from within an Amazon RDS for PostgreSQL database via stored procedures or user-defined functions. This allows you to extend the capabilities of the database and invoke external applications to act upon data changes. For example, you can create a Lambda function that sends emails to customers whenever their address in the database is updated. Lambda functions can be invoked either synchronously or asynchronously. For more details, read the Amazon RDS for PostgreSQL documentation.
