know bug :( - your variable names are in collision with column names.
You have to protect self - use prefixes for variables
postgres=# create table a(a varchar, b int);
CREATE TABLE
postgres=# insert into a values('kuku',10),('juku',20);
INSERT 0 2
postgres=# create function f(out _a varchar, out _b integer) returns
setof record as $$begin return query select * from a; return; end; $$
language plpgsql;
CREATE FUNCTION
postgres=# select * from f();
_a | _b
------+----
kuku | 10
juku | 20
(2 rows)
