Overview of PostgreSQL

What is PostgreSQL?
PostgreSQL is an advanced open-source object-relational database system with a strong focus on extensibility and compliance with SQL standards.

Key Features:

Advanced Data Handling: Supports complex data types and handles multiple tasks efficiently.
Extensibility: Allows users to define custom data types, functions, and even develop plugins.
SQL Compliance: Closely adheres to SQL standards, more so than MySQL.
