Two thoughts:

1. Make the array types only when someone actually uses them (create a
table with it or something).

2. Make a command: CREATE TYPE ARRAY OF "foo";

The latter has the benefit of not restricting it to an arbitrary choice
of types, you could accept both domains and composite types here. I
don't think it's unreasonable to require people to predeclare their
usage of array-of-compostite-type.

Perhaps change the word "CREATE" to "DECLARE". I'm thinking of the
explicit declaration of shell types as precedent here.

Have a nice day,
