Description
🔹 Mastering the DEFAULT Keyword in PostgreSQL INSERT 🔹

When inserting data into a PostgreSQL table, the DEFAULT keyword allows you to use predefined column values instead of manually specifying them. This approach helps maintain data integrity, avoids NULL values, and simplifies data entry.

📌 What You’ll Learn:
✅ What is the DEFAULT keyword in PostgreSQL?
✅ How to use INSERT INTO ... DEFAULT VALUES
✅ When to use DEFAULT instead of specifying values
✅ How DEFAULT helps avoid NULL values in your tables
✅ Performance benefits of using DEFAULT in data insertion

Using the DEFAULT keyword ensures efficient data entry, especially when dealing with large datasets. PostgreSQL automatically assigns the default values defined in your table schema, making your queries cleaner and more manageable.

💡 Pro Tip: Combine DEFAULT with ON CONFLICT for better control over duplicate entries!
