Indexing for LIKE Queries in PostgreSQL

The text discusses various ways to optimize LIKE queries in PostgreSQL, including indexing with range scans for prefix patterns, using expression indexes for case-insensitive comparisons, leveraging reverse functions to transform suffix patterns into prefix patterns, and utilizing GIN indexes on trigrams for generic full-text searches. It also touches on performance and scalability considerations, emphasizing the importance of understanding execution plan complexities and optimizing storage systems like YugabyteDB accordingly.
