I think this is just wishful thinking. resowners are backend-private, and they are robust as long as they are managing files accessed by a single backend. Trying to bend them into some kind of a state where they can manage a resource shared across multiple cooperating backends is fundamentally changing the model. What matters is not whether the old model was any good but whether the new one is any good. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
