Indexing is one of the most powerful tools for optimizing database performance. PostgreSQL, a robust and feature-rich relational database, offers a variety of indexing techniques to speed up query performance.
In this article, we’ll dive deep into the different types of indexes available in PostgreSQL, explore their use cases, and provide real-world examples to help you understand when and how to use them effectively.
What is Indexing?
An index in PostgreSQL is a data structure that improves the speed of data retrieval operations on a database table. In simple words think of it as the index of a book instead of scanning every page to find a topic, you can quickly locate it using the index.
However, just like a book index, database indexes come with a trade-off — they consume additional storage and can slow down operations (like INSERT, UPDATE, and DELETE).
