Ok, thank you, guys. What is the best way to make an array out of a
column? I didn't make up anything better then writing a function:
CREATE OR REPLACE FUNCTION int_column_to_array(query text) RETURNS int[]
AS $$
DECLARE
arr int[];
rec int;
BEGIN
FOR rec IN EXECUTE query
LOOP
arr := array_append('{}',rec);
END LOOP;
RETURN arr;
END;
$$ language plpgsql;
hannu=# select ARRAY(select usename from pg_user);
?column?
-------------------------------
{postgres,hannu,m1,skyncuser}
(1 row)
Lots of thanks! I tried the same one, but with ARRAY[], so i didn't get
anything.
