[GENERAL] RETURNS TABLE function returns nothingness

[Alexander Farber]

Good evening,

please help me to figure out, why doesn't this simple test function return
a row with 42, NULL values:

CREATE OR REPLACE FUNCTION words_merge_users_2(
                IN in_users jsonb,
                IN in_ip inet
        ) RETURNS TABLE (
                out_uid integer,
                out_banned varchar
        ) AS
$func$
DECLARE
        _user          jsonb;
        _uids          integer[];
        _created       timestamptz;
        _vip           timestamptz;
        _grand         timestamptz;
        _banned_until  timestamptz;
        _banned_reason varchar;
BEGIN
        out_uid := 42;
END
$func$ LANGUAGE plpgsql;


Here I call it at PostgreSQL 9.5.4 prompt in MacOS:

# select * from
words_merge_users_2('[{"given":"Abcde","social":1,"auth":"07f0254f5e55413dec7f32c8ef4ee5d3","stamp":1470237061,"female":0,"sid":"11111"}]
                  '::jsonb, '1.1.1.1'::inet);
 out_uid | out_banned
---------+------------
(0 rows)


Thank you (I am probably missing something very obvious)
