In the meantime, those who want arrays of non-integer datatypes
must cast to an array of the appropriate datatype (as suggested
by the documentation.)

create or replace function kop.bar()
returns date[]
language plpgsql
as $func$
declare
y date[] := CAST ('{}' AS date[]);

begin
y[1] := '1979-03-01';
y[2] := '1979-03-02';
y[3] := '1979-03-03';

return y;
end;
$func$;
