Well the database files are always encrypted, with using a encrypted 
file system, there is an unencrypted view of the files visible.

I realise that under normal setup this is readable by only the 
postgres user, and if you could read the files you would also be able 
to interrogate the server to get the data.

But if the postgres server wasn't running yet (i.e. the password 
hadn't been entered), there would be no data visible.

I don't know anything about Windows, does it have the same file 
security as Linux?

I realise the difference is small.
