How to Switch from SQLite to PostgreSQL in Django: A Step-by-Step Guide
Upgrade your Django project for production with PostgreSQL — a robust, scalable, and production-ready database.

🧠 Why Move from SQLite to PostgreSQL?

SQLite is an excellent choice for lightweight development and testing due to its simplicity and zero-configuration setup. However, it's not designed for production-scale applications. PostgreSQL, on the other hand, is a powerful, open-source object-relational database system that offers advanced features like:

* Data integrity & ACID compliance

* Concurrency control

* Full-text search

* Indexing & performance optimization

* Scalability for large datasets

If you're planning to deploy your Django project, switching to PostgreSQL is a smart move.

🚀 Prerequisites

Before switching databases, ensure: * PostgreSQL is installed on your system or server. * You’ve created a PostgreSQL database and user with permissions. * You’ve backed up your current SQLite data if needed. ⚙️ Install psycopg2 (PostgreSQL Adapter)

bash
pip install psycopg2-binary

🔧 Update settings.py to Use PostgreSQL
python
# settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'your_db_name',
        'USER': 'your_db_user',
        'PASSWORD': 'your_db_password',
        'HOST': 'localhost',  # or your DB server
        'PORT': '5432',
    }
}

📦 Migrate Your Database

Once your settings.py is updated, run:

bash
python manage.py makemigrations
python manage.py migrate

📤 Optional: Dump Data from SQLite and Load into PostgreSQL
bash
# Dump data from SQLite
python manage.py dumpdata > db.json

# Migrate the PostgreSQL schema
python manage.py migrate

# Load data into PostgreSQL
python manage.py loaddata db.json

✅ Verify Everything Works

Run your development server and test key features:

bash
python manage.py runserver

🎯 Conclusion

Switching from SQLite to PostgreSQL is a crucial step when moving your Django project from development to production. PostgreSQL’s advanced capabilities will help your application scale, perform, and remain stable in real-world scenarios.
