Woh, I was not aware that worked, e.g.:

test=> SELECT pg_language.*::text FROM pg_language;
pg_language
-------------------------------------
(internal,10,f,f,0,0,2246,)
(c,10,f,f,0,0,2247,)
(sql,10,f,t,0,0,2248,)
(plpgsql,10,t,t,12319,12320,12321,)

Any idea where this should be documented. It is useful?
