PostgreSQL

PostgreSQL (Postgres) is a powerful, open-source object-relational database system. It is known for its reliability, feature robustness (JSONB, GIS, Full Text Search), and performance.

When to Use

• Primary Database: The default choice for almost any modern application (Django, Rails, Node).
• Complex Data: When you need Relational + JSON (NoSQL) + Geo-spatial (PostGIS) in one DB.
• Data Integrity: When strictly typed schemas and ACID compliance are critical.

Quick Start

-- JSONB column usage
CREATE TABLE events (
    id SERIAL PRIMARY KEY,
    data JSONB
);
