I'm needing to do something like this from one server to another.. the hard drive is 100% full and I can't bring myself to pay $310 to DO for a 900GB server just to dump the DB which needs to be thinned down. which come to find out even if I remove table entries for hours, postgres can't do the vacuum to return GB apparently unless it has another 360GB or so to do what it needs doing I guess. So looking to pg-dump to a different server in a cheaper datacenter. Think I have something bookmarked talking about running rsync or something. Will be going into those options this week.
