Yes. A table alone is itself part of a partition set, so the result
should be made of only itself.

There could be value in having a version dedicated to inheritance trees
as well, true enough. As well as value in having something that shows
both. Still let's not forget that partition sets are structured so as
the parents have no data, so I see more value in having only partitions
listed, without the INHERIT part. Opinions from others are of course
welcome.
