08.11.2026 - plx : Write PostgreSQL functions in the language you already know.

What plx is

plx is a PostgreSQL extension that lets you write stored functions and triggers in the dialect you already know (the current set is listed below). When you run CREATE FUNCTION, plx transpiles the body to plpgsql and stores that plpgsql in pg_proc.prosrc. At run time the function is executed by PostgreSQL's own plpgsql interpreter. There is no separate language runtime loaded into the backend, and nothing new to run in production.
