I thought I had too many mallocs, but when I started looking, I couldn't
find the second one anymore.  I see it now, and fixed.  Looped through
cell and free'ed:

    for (i = 0; i < PQntuples(res); i++)
        free(cells[i * cols + 2]);
    free(cells);

    test=> \du
                    List of Users
     User Name | User ID |       Attributes
    -----------+---------+------------------------
     demouser2 |     140 | create DB
     postgres  |     139 | create user, create DB
