Over sometimes very bad trans-pacific internet connections
rsync -avPz --timeout=7777 --exclude '.?*.*' --exclude "temp*"
Many files where nothing changes goes very fast.
Large files with a few scattered changes throughout the middle
will go rather slowly. Usually instructive just to watch it and
see what happens.
Just a guess, but take a look at whatever the contents of pg_dump
actually look like. In particular, compare one dump to another
taken later. You might spot something obvious.
