Right now I am trying to dump the database, gzip, move across, and

the initial setup). Ideally I do this dump, move and import during a
period of inactivity on the master so the new server will come up and
immediately be able to catch up on replication due to lack of
activity. However, I have been importing the current db as a test and
after 90 minutes it seems to have only got 2/3 of the way. I am not
confident this will work but it seems like the most efficient way to
start.
you can't use pg_dump to create a slave, as it won't have the same timeline.
I would use pg_basebackup, but in general streaming replication over a
high latency erratic link will never work real well.
