In my opinion, what it shouldn't do is to drop the table by default ;-)

Are you planning to improve the function to allow to continue updating
topology if new data was added for example?

I think the case for the "clean" flag are:

* clean = True
-> topology exists already -> drop and recreate topology without warning?
-> topology doesn't exist -> create it

* clean = False
-> topology exists already -> update topology?
-> topology doesn't exist -> create it

Correct?

Daniel
