Description
💡 Looking for flexibility in string storage? Meet VARCHAR — PostgreSQL’s go-to data type for dynamic-length strings!

In this video, we break down the behavior and best practices of VARCHAR(n) and VARCHAR without a length limit. You'll learn:

How VARCHAR stores strings efficiently without space padding

What happens when a value exceeds the defined length (error vs. explicit cast)

When to use VARCHAR(n) vs. unbounded VARCHAR

Real-world examples like storing names, product titles, and user input

Common pitfalls with truncation and performance myths

🎯 If you're used to blindly choosing VARCHAR(255), this video will change how you approach string types in PostgreSQL forever.

📌 Learn why VARCHAR is often more practical than CHAR, and how it compares to the powerful TEXT type.

Stay tuned till the end for smart storage strategies and PostgreSQL design tips!
