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.
