We should also keep in mind that people who use range types can and likely will define their own convenience functions.
If people use singletons, or open ranges, or closed ranges, or one-hour timestamp ranges frequently, they can make
theirown notational shorthand with a 3-line CREATE FUNCTION statement. We don't need to have it all in core.
