Gevik,
The link didn't help because that is not the same problem as I have:
My problem is that it seems that in postgresql you can't use a parameter bo=
und to BYTEA data in the WHERE clause of the SQL statement.
So in my case: "SELECT x FROM T WHERE BinData =3D ?" does not work (return =
code -1) if the parameter bound to the ? is of type BYTEA.
