pg_dump and DEFAULT column values

I have a function and a table:

create table foo (
f1 integer default foo_func();
);

create function foo_func returns integer
as 'select max(f1)+1 from foo'
language 'sql';

when I use pg_dump, and then psql (\i <dumpfile>) to dump/reload
everything, table foo can't be created because it uses foo_func which
can't be created because it uses a table (foo) which doesn't exist.

So I always have to hand-edit the dump file:

create table foo (
f1 integer;
);

create function foo_func returns integer
as 'select max(f1) from foo'
language 'sql';

alter table foo alter column f1 set default foo_func();

Is there a way for pg_dump to do this automagically? or should I define
the table and function differently? Should the default value be
replaced with an on insert trigger?
