bytea might be theoretically the best choice, but the fact remains that
99% of the entries will be text that's readable in the user's encoding
(whatever that is). bytea will just be a serious PITA because of its
escaping issues. Also, the fact that 8.5 may change to hex display by
default will make bytea even more of a PITA for mostly-text data.
So I think Bacula's choice to use sql_ascii with text columns is
entirely defensible.

What concerns me is the claim that PG made a database with some
arbitrary parameters after having rejected a now-considered-invalid
command. I frankly do not believe that, but if it did happen it's
a *serious* bug that requires investigation.
