Thank you, George and Phillip! I was trying something similar (doing
a cast) which wasn't working:
SELECT array_to_string( (SELECT name FROM pseudonyms WHERE
person_id=125)::array, ' ');
In the meantime, I wrote a little function to do the job, but your
solution is simpler:
CREATE OR REPLACE FUNCTION persons.aggregatenames(personid integer)
RETURNS text AS
$BODY$declare
somerow record DEFAULT '';
thenames text;
BEGIN
FOR somerow IN SELECT name FROM pseudonyms WHERE person_id=personid LOOP
thenames := thenames || ' ' || somerow.name ;
END LOOP;
RETURN thenames;
END;$BODY$
LANGUAGE 'plpgsql' STABLE;
> SELECT array_to_string(array(SELECT name FROM pseudonyms WHERE
> person_id=125), ' ');
