PL/pgSQL (Procedural Language/PostgreSQL) is a procedural programming language supported by the PostgreSQL ORDBMS. It closely resembles Oracle’s PL/SQL language. With PosgreSQL v9.X some ISO SQL/PSM features like overloading of SQL-invoked functions and procedures are supported.PL/pgSQL as a fully featured programming language allows much more procedural control than SQL including the ability to use loops and other control structures.
