That seems surprising, because there's one PROCLOCK for every combination of a process and a lock. But, a process can't be waiting for more than one lock at the same time, because once it starts waiting to acquire the first one, it can't do anything else, and thus can't begin waiting for a second one. So I would have thought that this would be recorded in the PROC. But I haven't looked at the patch so maybe I'm dumb. -- Robert Haas EDB: http://www.enterprisedb.com
