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)
So what yo need is
select * from
gather_friend_info_from_all_partitions(get_friend_id_list_form_user_partition(user_id));
Yes, after using arrays, I figured out perfectly, how to do that. And
thanks for the help!
