pg_dump: version 10.3

I have created a policy with a comment on it.  pg_dump does not dump
the comment.

Here is my entire schema definition:
--------------------------------------------------------------------
    create table rls (
      username text not null,
      details  text not null
    );

    create policy only_owner on rls
      for all
      to session_user
      using (username = user)
      with check (details != 'xyzzy');

    comment on policy only_owner on public.rls is 'Another comment';
--------------------------------------------------------------------

pg_dump extracts the table and policy but not the comment.

I can manually extract the comment with a query:

    select p.polname, 
           quote_literal(obj_description(p.oid, 'pg_policy')) as comment
    from pg_catalog.pg_policy p;

Initially tried with postgres server 9.5.21 running from psql 10.3.
Also
tried with postgres server 10.3 running from psql 10.3.

I am not at all anxious for this to be fixed.  Just thought you should
know.
