By the same token, you might want to use ROW() rather than
composite-type literal syntax for the array elements.

I think also that casting the array, rather than the individual rows,
only works as of 8.4; ie in 8.3 you have to follow the first example:

> SELECT print_array(ARRAY[ '(1,"abc")'::typ1, '(2,"def")'::typ1 ]);
> SELECT print_array(ARRAY[ '(1,"abc")', '(2,"def")' ]::typ1[]);

In this case there's not much real difference, but with a lot of
array elements the individual casts get tedious.
