I would like to add that parent_store may be redundant if we ever include the
pg84 enhancements. Storing the parent_left and parent_right may speed up
_reading_ of the tree, but will put a heavy burden on writing or modifying the
tree. Postgres, as of 8.4, can offer an alternative efficient way to perform
searches in tree-structured data.
