    There's one PGPROC per process. There's one PROCLOCK for each process
    and each lock that that process has any interest in (ie, either
    currently holds or is waiting for).

    The comments for these structs seem to be a bit of a mess at the moment :-(
    Bruce renamed the struct types recently, but appears not to have done a
    good job of adjusting the comments to match. It may help to know that
    a proclock object was formerly called a "holder".

    regards, tom lane
