Bug in CVS pg_dump against 7.0.x

Hi,

I know 7.0.x is pretty old, but I'm wondering if we should fix this to
make it better for people upgrading.

If you create a table like this in 7.0.x:

CREATE TABLE address (
first_name character varying(50) DEFAULT 'asdf' NOT NULL,
last_name character varying(50) NOT NULL,
address character varying(50),
tesing character varying[]
);

The 7.5 pg_dump program will dump it like this:

CREATE TABLE address (
first_name character varying(50) DEFAULT 'asdf' NOT NULL,
last_name character varying(50) NOT NULL,
address character varying(50),
tesing _varchar
);

I have attached a patch that should fix it. I haven't been able to
actually test it since my dev machine and the 7.0 machine I have access
to aren't connected - although it does compile. The fix is based on the
7.0 psql code.
