Comments on roles are stored against the pg_authid catalog relation

Hi. What do you mean? COMMENTs are not stored *in* that relation.
And AFAIK, only accessible via functions using the OID or NAME.

So the relation used, pg_authid or pg_roles, shouldn't matter, no?

OK, I see now you meant shobj_description(oid, 'pg_authid'),
i.e. that 'pg_authid' literal in the function call. Thus your use of
"against" in the above sentence. Apologies for my misunderstanding.
 
But that literal in the function call is separate from which relation,
pg_authid or pg_roles, one actually SELECT from, as already shown. --DD

```
select ...,  shobj_description(oid, 'pg_authid')
  from pg_roles
...
```
