Introduce a SQL-callable function array_sort(anyarray). Create a function that will sort the elements of an array according to the element type's sort order. If the array has more than one dimension, the sub-arrays of the first dimension are sorted per normal array-comparison rules, leaving their contents alone.
In support of this, add pg_type.typarray to the set of fields cached by the typcache.
