Yes, that is how PostgreSQL 9 represents bytea data.

Mail text does not have any inherent character set, it is just a
bunch of octets. Decoding into character sets is done for each
mail MIME part according to its MIME Content-Type.

If you'd just like a quick glimpse of  mostly readable text,
you may encode these octets in escape notation, or force
them to be interpreted as Latin1 (even though they are not
necessarily such).

Something like:

select encode(mail_text,'escape') from quarantine
  where partition_tag=30 and mail_id='qAlfKSwhxCsk'
  order by chunk_ind asc;
