You're not guaranteed to get a recoverable database from a filesystem
backup unless you (a) take Postgres down during the backup, or (b) use
point-in-time recovery (which is documented in the manual). So what
you're doing now isn't actually saving your data for you.
I would definitely go the pg_dump route unless you want to set up
PITR...
