You don't need select into here - the sample below deletes everything older
than one day. You should be able to adapt it to your needs. Your example had
a + rather than a - which would delete things in the future, that might have
been what you intended, or it might not.

The RAISE NOTICE line prints a useful debug value. I like to scatter these
around while I'm testing.

CREATE FUNCTION del_old_history() RETURNS int4 AS '
DECLARE
var_history_age_limit int4;
set_time timestamp;
BEGIN
var_history_age_limit:=1;
set_time := current_date() - (var_history_age_limit::text || '' days
'')::interval;
RAISE NOTICE ''set time = %'',set_time;
delete from history where complete_time <= set_time;

return var_history_age_limit;
END;'
LANGUAGE 'plpgsql';
