Commit acb7e4eb6b1c added a new implementation for PQsendQuery so that it works in pipeline mode (by using extended query protocol), but it behaves differently from the 'Q' message (in simple query protocol) used by regular implementation: the new one doesn't close the unnamed portal. Change the new code to have identical behavior to the old.
