In case of durable transactions, would they be released from memory? Thus
could the transaction be more respectfull to the HW when processing too
much data?

And what about nested transactions? Are they planned? The point is
connected to my previous question of the secured access to stored
procedures. If I move part of database logic to the client, I will have to
introduce parameters to the procedures. This may be potentialy abusable.

If I try to use dblink from server to server (both are the same), is there
some perfromance penalty? How big?
