An RSet has no Database as context, so as written that certainly isn't
possible - you'd need a Database parameter to each method or some other
approach.

Note this isn't what has been requested - Andreas is wanting to know
this information for terms in the ESet, and in that case we're already
doing the work required to calculate the "rtermfreq" anyway so the
natural API change would be to add a "get_rtermfreq" method to
ESetIterator.
