In psql, avoid leaking a PGresult after a query is cancelled.
After a query cancel, the tail end of ExecQueryAndProcessResultstook care to clear any not-yet-read PGresults; but it forgot aboutthe one it has already read. There would only be such a resultwhen handling a multi-command string made with "\;", so that you'dhave to cancel an earlier command in such a string to reach thebug at all. Even then, there would only be leakage of a singlePGresult per cancel, so it's not surprising nobody noticed this.But a leak is a leak.Noted while re-reviewing90f5178, but this is independent of that:it dates to7844c99. Back-patch to v15 where that came in.
