PostgreSQL Stored Procedures
PostgreSQL stored procedures are user-defined functions written in languages like PL/pgSQL, SQL, or others, that are stored and executed within the PostgreSQL database server. They encapsulate complex business logic, data validation, or repetitive operations, allowing for modular and reusable code directly in the database. This enhances performance by reducing network overhead and ensures data integrity through server-side processing.
Developers should learn PostgreSQL stored procedures when building applications that require complex data manipulation, such as financial systems, reporting tools, or applications with heavy transactional logic, as they improve efficiency by executing operations close to the data. They are particularly useful for enforcing business rules, automating tasks like data cleanup or aggregation, and enhancing security by centralizing logic to prevent SQL injection and reduce client-side code complexity.
