A single database connection ususally maps to a single session. A connection pool is logically also a session pool. Most sessions have a way to reset the session state which is desirable to prevent one bad query from poisoning another later query with temp table name conflicts or other persistent session resources. It also lets drivers provide users with better error messages from queryies when the underlying transport or query method fails. Internally the driver connection should now be marked as bad, but return the actual connection. When ResetSession is called on the connection it should return driver.ErrBadConn to remove it from the connection pool. Previously drivers had to choose between meaningful error messages or poisoning the connection pool. Lastly update TestPoolExhaustOnCancel from relying on a WAIT query fixing a flaky timeout issue exposed by this change.
