I don't think you will ever be happy if you try to use a bit field to
store binary data. Use bytea [1] instead (the 'lo' type has the
disadvantage the the data is not stored inside the table).
Note that the support for BIT VARYING was dropped in SQL:2003 [2].
SQL:2003 has the BLOB datatype to store binary data and SQL:2008 will
have 2 new types: BINARY and BINARY VARYING.
