How do I create an array and then put a result of a function into it?
I'm doing it like this:

array text[];
select regexp_split_to_array('whatever this is it splits into array with spaces', E'\\s+')
    into array;

But obviously it doesn't work, when I try to

raise notice '%', array[1];

It's just not how it's done.

array is a reserved word. You cannot use it as variable name in plpgsql. This works:

DO
$do$
DECLARE
   _arr text[];
BEGIN
SELECT regexp_split_to_array('thiiis splits into array with spaces', '\s+')
INTO _arr;

RAISE NOTICE '%', _arr[1];
END
$do$;

SQL Fiddle

Also simplified E'\\s+' -> '\s+'.
standard_conforming_strings = ON is the default since Postgres 9.1 and should be the universal setting by now.
