The pg_restore change looks good -- that was clearly wrong.

Also, +1 for the new note in pg_dump.

For COPY, I think perhaps it would be more logical to put the new note
immediately after the third note which describes the privileges
required, since it's kind of related, and then we can talk about the
RLS policies required, e.g.:

    If row-level security is enabled for the table, COPY table TO is
    internally converted to COPY (SELECT * FROM table) TO, and the
    relevant security policies are applied. Currently, COPY FROM is not
    supported for tables with row-level security.

I think so, yes, because that makes it clearer what policies will be applied.
