You should use IN/OUT - Parameters, foro example:

test=# create or replace function atif(in int, in text, out a int, out b text) returns record as $$begin a=1; b='hello world'; return; end;$$language plpgsql;
CREATE FUNCTION
test=*# select * from atif(0,'test');
a | b
---+-------------
1 | hello world
(1 row)
