When single row mode is enabled, after retrieving part of the result set, I'm no longer interested in the rest of it (due to error handling or other reasons). How can I discard the result set without repeatedly calling PQgetResult() in such situation ?
The result set may be quite large and it's inefficient to call PQgetResult() repeatedly, so it's necessary to do so sometimes.

Thanks

I think you should use PQcancel().

is not better to use a cursor for this use case?
