commit    66b14030e889f09b49b3be9b93d63a00289d73c7
Author:   Robert Haas <rhaas@postgresql.org>
Date:     Mon Aug 16 02:02:28 2010 +0000

    Make LockDatabaseObject() AcceptInvalidationMessages().
    
    This is appropriate for the same reasons we already do it in
    LockSharedObject(): things might have changed while we were waiting
    for the lock.  There doesn't seem to be a live bug here at the moment,
    but that's mostly because it isn't currently used for very much.
