: A procedural language that lets you write functions and triggers directly in Python inside the database.

The phrase you're referencing likely refers to a well-known technical talk by Christophe Pettus (CEO of PostgreSQL Experts, Inc.).

: Includes native support for arrays , ranges , and HSTORE (key-value pairs), which maps naturally to Python lists and dictionaries.

Based on this specific talk and the related content on thebuild.com, these features are highlighted as essential for Python developers:

: Allows Python developers to store semi-structured data (like dicts) while maintaining the benefits of a relational database.

: Unlike some other databases, PostgreSQL stays very close to the ANSI SQL standard, making it a predictable "solid" choice for production applications.
