The easier way was already provided in this message:

http://archives.postgresql.org/pgsql-general/2011-09/msg00277.php

Specifically:

psql -h <host1> ... -c 'copy (select ... from <tablename> where ...)
to stdout' | psql -h <host2> ...  -c 'copy <tablename> from stdin'

(where '...' are other psql's options like user, db, ...)
