Can you use a default to allow the user to specify the default value for
an element? May look a little strange, though, if the user specifies a
default array and a default element value, like:
CREATE TABLE ARR(ARR CHAR(30)[] DEFAULT '{"hello", "good bye"}' NULL);
So the first default is the array default; specify NULL if you don't
want one but do want an array element default; the second, if present,
is the array element default. I'm not sure I like this or not, but it's
an idea.
