      When you SELECT bytea type, PostgreSQL returns octal byte value
      prefixed by \ (e.g. \032). Users are supposed to convert back to
      binary format by yourself.
     </P
><P
>&#13;      This function requires PostgreSQL 7.2 or later. With PostgreSQL
      7.2.0 and 7.2.1, bytea type must be casted when you enable
      multi-byte support. i.e. <VAR
CLASS="literal"
>INSERT INTO test_table (image)
      VALUES ('$image_escaped'::bytea);</VAR
> PostgreSQL 7.2.2 or
      later does not need cast. Exception is when client and backend
      character encoding does not match, there may be multi-byte
      stream error. User must cast to bytea to avoid this error.
