create function sort(anyarray)
returns anyarray as $$
select array(select $1[i] from generate_series(array_lower($1,1),
array_upper($1,1)) g(i) order by 1)
$$ language sql strict immutable;
postgres=# select sort(array[1,2,3,1]);
sort
-----------
{1,1,2,3}
(1 row)
postgres=# select sort(array['a','b','c','a']);
sort
-----------
{a,a,b,c}
(1 row)
