I want to know which column undefined when "undefined_column" Happen
at run time.


With libpq you can call PQerrorMessage(), PQresultErrorMessage(),
or PQresultErrorField() to get a string that should identify the
offending column, function, table, etc.  Will that work for your
purpose?

No. I want to throw a exception with the column name, like this :

if (sqlstate == undefined_column)
throw UnknownProperty(column_name);
