> The patch fixes this issue by calling CallableStatement.getBigDecimal(parameterPosition).intValue() instead of CallableStatement.getInt(paramterPosition).
> I studied JDBC3 specification whether PostgreSQL driver is wrong
> or not and I think that the driver is correct. There is a conversion table
> on page B-182 which should correspond to ResultSet object getter
> methods only. There is nothing about the conversion being done
> in CallableStatement's getter methods.
> Hibernate should use CallableStatement.getBigDecimal(parameterIndex).intValue()
> to obtain a value of a output parameter of NUMERIC data type.
