Not if you have enabled PITR and tell the database that you do so:

Works excellent..

That's true - I forgot about pg_start_backup / pg_stop_backup (which is sad considering I use them every time I roll a new slave...)

Doing the backup that way avoids the outage in my filesystem snapshotting example and isn't dependent on OS-level capabilities so it's definitely a better way to go.
