Is it possible?
From what I tried it is possible to create such a function but it is not
possible to call it ?!
Can anyone provide an example?
Tnx.

create table foo (f1 int, f2 text);
insert into foo values(1,'a');
insert into foo values(2,'b');
insert into foo values(3,'c');
create or replace function get_foo(int) returns foo as 'select * from
foo where f1 = $1' language 'sql';
create or replace function use_foo(foo) returns text as '
declare
v_foo alias for $1;
begin
return v_foo.f2;
end;
' language 'plpgsql';
regression=# select use_foo(get_foo(2));
use_foo
---------
b
(1 row)
HTH,
Joe
