Show the requested lock level and the object being waited on, in the same format we use for deadlock reports and similar errors. This is particularly helpful for debugging lock-timeout errors, since otherwise the user has very little to go on about which lock timed out. The performance cost of setting up the callback should be negligible compared to the other tracing support already present in WaitOnLock. As in the deadlock-report case, we just show numeric object OIDs, because it seems too scary to try to perform catalog lookups in this context.
