Good point --- actually he could convert it back to the original
subselect style, as long as he's using the correct operator:

SELECT * FROM c WHERE ARRAY[col1] <@ ANY(SELECT col2 FROM c);

The one-element-array trick seems a bit awkward though.  I wonder
why we don't have an "anyelement <@ anyarray" kind of operator...
