• B-Tree Index: This is the default index type in PostgreSQL and is well-suited for equality and range queries. B-Tree indexes are highly versatile and perform well on various types of data. 
• Hash Index: Hash indexes are effective for exact match lookups but are less useful for range queries or pattern matching. 
• GIN (Generalized Inverted Index): GIN indexes are ideal for complex data types like arrays and full-text search. They efficiently handle queries that involve containment and overlap. 
• GiST (Generalized Search Tree): GiST indexes provide versatile geometric and text search capabilities and are suitable for various types of complex queries. 
• SP-GiST (Space-Partitioned Generalized Search Tree): SP-GiST indexes are optimized for multi-dimensional data and are useful for spatial and network-based queries.
