It doesn't support it yet, but you can probably trivially add a method for it. Time (timestamp, interval) types might require more changes since the type factories are not always parameter-less. A small note, this functionality (random generation) is part of the testing shared library. AFAIK this is _not_ exported in the binary packages.
