The best Postgres feature you're not using – CTEs aka WITH clauses

This technical article introduces Common Table Expressions (CTEs), also known as WITH clauses, in PostgreSQL. It argues that CTEs are an underused feature that can make SQL more readable and composable, similar to principles in other programming languages. The article provides a practical example, demonstrating how to break down a complex query (finding users responsible for over 50% of tasks on a project) into clear, logical steps using multiple CTEs.
