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

No. I want to throw a exception with the column name, like this :<br>
<br>
if (sqlstate == undefined_column)<br>
throw UnknownProperty(column_name);<br>
<br>
