PL/Lua is an implementation of Lua as a loadable procedural language for PostgreSQL: with PL/Lua you can use PostgreSQL functions and triggers written in the Lua programming language. PL/Lua brings the power and simplicity of Lua to PostgreSQL, including: small memory footprint, simple syntax, lexical scoping, functions as first-class values, and coroutines for non-preemptive threading.
