Can anybody spot the problem with this function? Or, how i'm calling it?
(it's not clear to me which it is)
CREATE TABLE member (
...
first_name character varying(64),
last_name character varying(64),
organisation character varying(128),
email character varying(128),
...
);
CREATE OR REPLACE FUNCTION fetcOnlineContacts() RETURNS SETOF record
AS $$
DECLARE
member_contact record;
BEGIN
FOR member_contact IN
EXECUTE 'SELECT DISTINCT ON (m.email)
m.first_name || '' '' || m.last_name AS name,
m.organisation, m.email AS address
FROM member AS m
WHERE m.email IS NOT NULL
ORDER BY m.email, m.last_name, m.organisation ASC'
LOOP
RETURN NEXT member_contact;
END LOOP;
RETURN;
END;
$$
LANGUAGE plpgsql IMMUTABLE;
test=# SELECT * FROM fetchOnlineContacts() AS (name text, organisation
text, address text);
ERROR: wrong record type supplied in RETURN NEXT

Normally, i declare a type, but this will be a single-use one so a
record seemed to be sufficient.
