BE carefull you have a number of limitation with recursive cte (I'm thinking of update and so.)
You can work around with plpgsql but it might be painfull.
You forgot a solution :
if you need powerfull graph features,
use postgres as a database and a SPARQL speaking frontend.
It may be a bit of overkill ;-)

Hi AlbanYes, you're right. In fact that's what I'm testing a way to replace, as I'm not confident in the performance in all situations. My fault entirely; I should have told so from the start.
