I disagree.  I think it's the purpose of documentation to be specific.
 The code says:

        /* Allow DROP to either table owner or schema owner */
        if (!pg_class_ownercheck(relOid, GetUserId()) &&
            !pg_namespace_ownercheck(classform->relnamespace, GetUserId()))
            aclcheck_error(ACLCHECK_NOT_OWNER, ACL_KIND_CLASS,
                           rel->relname);

So the command can be executed by the owner of the table, the owner of
the containing schema, or the superuser.

That seems simple enough.
