This article discusses various types of indexes supported in Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL, including GIN, GiST, HASH, and BRIN indexes. It provides an overview of each index type and their use cases.

Specifically, the article covers:

• GIN (Generalized Inverted Index) index: Used for searching composite values like arrays, JSON, and full-text search
• GiST (Generalized Search Tree) index: Used for range queries, full-text search, and geospatial data
• HASH index: Suitable for equality lookups, useful for unique constraint enforcement and join operations
• BRIN (Block Range Index) index: Efficient for ordered datasets and time-series data, stores min-max values for block ranges
