Currently when processing theSimpleQueryMessage, if there are noDataRows coming from postgres the column data is inaccessible since the data is embedded in theSimpleQueryRow. In particular, this makes it difficult if you're displaying user submitted or dynamic query results where being able to determine the columns from the query after it's been sent to the server would be useful. Adding an enum value ofRowDescription(Arc<[SimpleColumn]>) would alleviate this since you could separately process the columns even without aDataRow being returned.
