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.
