ERROR: a column definition list is required for functions returning "record"

I have a plpgsql function that returns dataset.
First it was defined to return SETOF someview.
Then I changed it to return SETOF RECORD, in order to be able to return
dataset with varying number of columns.
But, I get the following error:"ERROR: a column definition list is required
for functions returning "record" SQL state: 42601".
What does it mean? What is "columns definition list"?

Thanks,

Zlatko

Hello

you have to specify column names and column types. Like

postgres=# create or replace function foog() returns setof record as $$
declare r record; begin r := row(10,20); return next r ; return; end;
$$ language plpgsql;

postgres=# select * from foog() t(a int, b int); a | b
----+----
10 | 20
(1 row)
