First phase of work on array improvements. ARRAY[x,y,z] constructor
expressions, ARRAY(sub-SELECT) expressions, some array functions. Polymorphic functions using ANYARRAY/ANYELEMENT argument and return types. Some regression tests in place, documentation is lacking. Joe Conway, with some kibitzing from Tom Lane.
