Robert Haas 3cba8999b3 Create a "fast path" for acquiring weak relation locks. ... When an AccessShareLock, RowShareLock, or RowExclusiveLock is requested on an unshared database relation, and we can verify that no conflicting locks can possibly be present, record the lock in a per-backend queue, stored within the PGPROC, rather than in the primary lock table. This eliminates a great deal of contention on the lock manager LWLocks. This patch also refactors the interface between GetLockStatusData() and pg_lock_status() to be a bit more abstract, so that we don't rely so heavily on the lock manager's internal representation details. The new fast path lock structures don't have a LOCK or PROCLOCK structure to return, so we mustn't depend on that for purposes of listing outstanding locks.
