In response to Kevin Kempter :

Yes, but keep in mind, COPY cant create the table on the destination. If
the destination contains a (empty) table it's no problem.
If the destination-db doesn't contain the table you can also use
pg_dump:
kretschmer@tux:~$ createdb new_test
kretschmer@tux:~$ pg_dump -t foo test | psql -X new_test -f -
SET

CREATE TABLE
ALTER TABLE
kretschmer@tux:~$ psql new_test -c "select * from foo"
