Giving this some thought, I'm curious what would be acceptable as an end
result, specifically related to how a query on pg_authid might look/work.
I was able to preserve the structure of results from pg_roles, however,
that same approach is obviously not possible with pg_authid.  So, I'm
curious what the thoughts might be on how to best solve this while
minimizing impact (perhaps not possible) on users.  Currently, my thought
is to have a builtin function called 'get_all_role_attributes' or similar,
that returns an array of each attribute in string form.  My thoughts are
that it might look something like the following:

SELECT rolname, get_all_role_attributes(rolattr) AS attributes FROM
pg_authid;

| rolname |             attributes              |
+---------+-------------------------------------+
| user1   | {Superuser, Create Role, Create DB} |

Another approach might be that the above function return a string of comma
separated attributes, similar to what \du in psql does.  IMO, I think the
array approach would be more appropriate than a string but I'm willing to
accept that neither is acceptable and would certainly be interested in
opinions.

Thanks,
Adam
