Well, it's maintained in the sense of "I don't know of any problems with
it." Right now all it does is implement the PERIOD data type, which is
indexable so that you can do searches on predicates like
"&&" (overlaps).

It may get a little more exciting when more features like temporal keys
(which I'm planning to make possible in the next commitfest) or temporal
joins (no serious plans yet, but seems doable) are implemented.
