36.7. Procedural Language Functions

Note: The following description applies both to Postgres-XL and PostgreSQL if not described explicitly.

Postgres-XL allows user-defined functions to be written in other languages besides SQL and C. These other languages are generically called procedural languages (PLs). Procedural languages aren't built into the Postgres-XL server; they are offered by loadable modules. See Chapter 39 and following chapters for more information.
