Welcome to PostgreSQL Learning

Welcome to PostgreSQL Learning#

Welcome to this learning space dedicated to PostgreSQL and modern relational database design.

This platform is being built to provide project-based PostgreSQL tutorials, where concepts are explained step by step and then applied to real-world database projects, not isolated SQL examples.

The focus is on understanding PostgreSQL as a complete system: server, databases, roles, security, storage, and performance.

What you’ll find here#

  • Beginner to advanced PostgreSQL tutorials

  • Project-level understanding of PostgreSQL architecture

  • PostgreSQL Server, Database, Schema, and Role concepts

  • Authentication, permissions, and security

  • Working with pgAdmin and psql

  • SQL fundamentals and advanced queries

  • Performance tuning and indexing

  • Backup, restore, and troubleshooting

  • PostgreSQL used in real applications (Django, APIs, production systems)

Who this is for#

  • Beginners starting with PostgreSQL

  • Developers who want deep understanding, not just queries

  • Backend engineers working with Django, APIs, and services

  • Anyone who prefers learning concepts + implementation together

How this documentation is structured#

PostgreSQL is explained using a top-down, project-level model:

  • Server (PostgreSQL instance)

  • Databases (project boundaries)

  • Schemas (organization layer)

  • Roles & permissions (security layer)

  • Tablespaces (storage layer)

  • Tables, indexes, views (data layer)

  • Tools (pgAdmin, psql)

This mirrors how PostgreSQL is organized internally and how it appears in pgAdmin.
