Michael, it sure did.  here is how i got it done on my
remote server with winxp as my local machine.

1. i signed on to my VPN (required to connect in this
case).
2. Start -> Run -> type "cmd" -> OK.
3. type "cd c:\program files/postgresql/8.1/bin" Note:
if this doesn't work type the same except enclose
program files in quotes so it looks like this "program
files".
4. type "pg-dump <your db name> -h <external host
running your db> -u > <your sql file name.sql>

the -u forces a username and password request.  w/o
it, your window's user account is assumed and only a
password is requested.  if you are logged into an
account that isn't also a database user on the remote
db, you can't log in.

5. User name: <type remote host username - postgres in
my case>
6. Password: <type remote host's username password>

7. after some processing - go look in c:\program
files/postgresql/8.1/bin for "your_sql_file_name.sql"
- it should be there.

i created the db and restored it exactly as Michael
suggested.  i didn't do a dump_all and i will manually
create a few roles rather than edit the my .sql file.

Michael, i noticed that you nomenclature:

psql -d foo2 -f foo-dump.sql

is different from the manual's:

psql -e foo < foo-dump.sql

can you please briefly explain the nuances at work
here?  i didn't find any pg-dump reference to your use
of the -f flag or the manual's use of the -e flag.

this is the link to the pg_dump page:

http://www.postgresql.org/files/documentation/books/aw_pgsql/node264.html

tia...  your guidance was very helpful to me and,
hopefully, others.
