Are you sure the EBS snapshot is consistent? if the snapshot is not consistent,enven on the same volume,you will have prolbems with your backup.
One methed can be try is run pg_start_backup() before take snapshot.

We're running on EBS volumes on EC2. We're interested in leveraging
EBS snapshotting for backups. However, does this mean we'd need to
ensure our pg_xlog is on the same EBS volume as our data?
(I believe) the usual reasoning for separating pg_xlog onto a separate
volume is for performance. However, if they are on different volumes,
the snapshots may be out of sync.
Thanks.
