    Skip other sessions' temp tables in REPACK, CLUSTER, and VACUUM FULL
    
    get_tables_to_repack() and get_all_vacuum_rels() were including other
    sessions' temporary tables in their output work list, causing REPACK,
    CLUSTER and VACUUM FULL (when executed without a table list) to attempt
    to acquire AccessExclusiveLock on them, potentially blocking for an
    extended time.  Fix by skipping other-session temp tables early, before
    they are added to the list.
    
    This issue is ancient, but there have been no complaints about it that I
    know of, so I'm opting for not backpatching at present.
