Actually, after sleeping on it, there could be potentially two problems:
1) We don't check the relkind of the relation.  For example it is
possible to get a tree from an index, which is incorrect.  I would
suggest to restrain the root relation to be either a relation, a
partitioned table or a foreign table.
2) What about the users who can have a look at a tree?  Shouldn't we
tighten that a bit more?  I am sure it is not fine to allow any user to
look at what a partition tree looks like, hence only the owner of the
root should be able to look at its tree, no?
