I know it's not wal-e, but Barman recently added support for streaming WAL from postgres, so in theory you shouldn't lose any data if the master crashes. Note that this does require a replication slot on the master to implement. <rant> It's also stupid that you still have to set up WAL shipping (e.g. via rsync or scp) before taking a base backup even if you have streaming replication enabled. </rant> That being said though, I have not been happy with the restore performance of barman, though admittedly this may be I/O related.
