Not really. I'm convinced, and not only for e_c_s, that autoconfiguration is within the realm of possibility. However, since such a statement holds little weight without a patch attached, I've been keeping it to myself (until I can invest the effort needed for that patch). In any case, as eavesdroppers can infer a cryptographic key by timing operations or measuring power consumption, I'm pretty sure postgres can infer cost metrics and/or time sharing with clever instrumentation. The trick lies in making such instrumentation uninstrusive. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
