There is no way to deparse a function body -- as far as the backend is concerned, the body is just an opaque string. That string is to be interpreted by the language handler only. I don't know if it's possible to do different for non-core PLs, but I do not think we have to worry about them in the Postgres implementation. -- Álvaro Herrera PostgreSQL Developer — https://www.EnterpriseDB.com/ "La victoria es para quien se atreve a estar solo"
