Hi! I am now in the process of choosing a Db for our next project. A central point is that objects have a distinct tree-like structure (parent-child chains). My question is whether there is anything I can do in Postgres that could provide a functionality similar to Oracle's CONNECT BY/START WITH in queries. Another problem is a performance of such a solution, if it exists. Basically, my choice is now either Oracle or Postgres but Postgres is more attractive because it's free and, quite frankly, Oracle would be an overkill for this particular project. Thanks much, Sergei
