You could call that function like this:

regression=# select home.* from home(3,4) as (f1 char(15), f2 int);
 f1 | f2
----+----
    |
(1 row)

regression=# select h.* from home(3,4) as h (f1 char(15), f2 int);
 f1 | f2
----+----
    |
(1 row)

Note that the AS clause must provide column names as well as types
for the function output.  I think the word "AS" is optional in the
second case but not the first.
