Auto-generation of range types isn't going to happen, simply because the
range type needs more information than is provided by the base type
declaration. (First, you need a btree opclass, and second, you need a
"next" function if it's a discrete type.)
By my count there are only about 20 datatypes in core for which it looks
sensible to provide a range type (ie, it's a non-deprecated,
non-composite type with a standard default btree opclass). For that
many, we might as well just build 'em in.
