I installed PL/pgSQL by default via initdb with the attached patch. The
only problem is that pg_dump still dumps out the language creation:
CREATE PROCEDURAL LANGUAGE plpgsql;
ALTER PROCEDURAL LANGUAGE plpgsql OWNER TO postgres;
What is odd is that I used the same process that initdb uses to create
other objects. Does anyone know why this is happening?
