This fixes pg_dump so that when using the '-O' no owners option it does not print the owner name in the object comment.
This fixes pg_dump so that when using the '-O' no owners option it does
not print the owner name in the object comment.

eg:

--
-- Name: actor; Type: TABLE; Schema: public; Owner: chriskl; Tablespace:
--

Becomes:

--
-- Name: actor; Type: TABLE; Schema: public; Owner: -; Tablespace:
--

This makes it far easier to do 'user independent' dumps.  Especially for
distribution to third parties.
