Log message:
    The "Allow easy display of usernames in a group (pg_hba.conf uses groups
    now)" item on the open items, and subsequent plpgsql function I sent in,
    made me realize it was too hard to get the upper and lower bound of an
    array. The attached creates two functions that I think will be very
    useful when combined with the ability of plpgsql to return sets.

    array_lower(array, dim_num)
    - and -
    array_upper(array, dim_num)

    They return the value (as an int) of the upper and lower bound of the
    requested dim in the provided array.
