CTE Performance Insights
CTEs, or Common Table Expressions, allow for more complex queries by abstracting subqueries, but their impact on performance varies by PostgreSQL version.

However, recent updates allow for more control over materialization, enabling developers to choose when it benefits their queries. Understanding this change can significantly enhance query performance and efficiency.In this clip
