How do I search a two dimensional array?

I can search a one dimensional array with SELECT value = ANY(array), but 
how do I search  two dimensional array for a particular row?  ANY seems 
to flatten out a two dimensional array.

[local]:playpen=> select 2 = any (ARRAY[[1,7],[4,2]]); ?column?
---------- t
(1 row)
