Yep.
Look at this:
drop table dupa cascade;
create table dupa (a int, b int, c int);
insert into dupa (a, b, c) values (1, 2, 3);
insert into dupa (a, b, c) values (2, 3, 4);
create or replace function ttt(int) returns record as '
declare
~ r record;
begin
~ select * into r from dupa where ($1=a);
~ return r;
end;
' language 'plpgsql';
And then:
ojciec=# select * from ttt(1) as foo(aa int, bb int, cc int);
~ aa | bb | cc
- ----+----+----
~ 1 | 2 | 3
Is this what you need?
