Either of the following should work in PostgreSQL 8.0 and later:
SELECT (decorate(x)).* FROM find() AS f(x);
SELECT (decorate(find)).* FROM find();
A downside is that decorate() will be called once for each output
column in each row, as can be seen by adding debugging RAISE
statements. So in your example it would be called eight times
(2 rows * 4 columns) instead of twice (once for each of 2 rows).
