        * HashAlgorithm.cs,
        NpgsqlAsciiRow.cs,
        NpgsqlBinaryRow.cs,
        NpgsqlClosedState.cs,
        NpgsqlCommand.cs,
        NpgsqlCommandBuilder.cs,
        NpgsqlConnection.cs,
        NpgsqlDataReader.cs,
        NpgsqlException.cs,
        NpgsqlParameterCollection.cs,
        NpgsqlReadyState.cs,
        NpgsqlTransaction.cs: Improved exception handling. Now Npgsql throws mor
e meaningful exceptions instead of throw NpgsqlException which are now exclusive
ly to sign server errors. Thanks Glen Parker (glenebob@nwlink.com) for the patch.
