create a new db using the current one as a template. Easy to do and speed is acceptable. A bit downtime is ok, but it's only on the current server. Is there a way to move it to anther server?
FWIW, I recently set up a 160GB clone by simply piping from pg_dump over the network into psql, alleviating the need to dump to disk. In my case, the server did not have enough space to hold the pg_dump, so I had to stream it.
