OK, that's reasonable. If potential memory leaks are only for the
duration of a transaction I'm not worried (in regard to the one
recursive function we're using) as it's cachable and our trees not very
deep.
I have found one bug that crashed the backend if a recursive function's
called. Are you interested in it, since folks can now define them
semi-officially (if a bit unconventially) via CREATE AND REPLACE?
