             Summary: Add vectorized executor extension and GNC
                 Key: HAWQ-1583
                 URL: https://issues.apache.org/jira/browse/HAWQ-1583
             Project: Apache HAWQ
          Issue Type: Sub-task
          Components: Query Execution
            Reporter: Hongxu Ma
            Assignee: Lei Chang
             Fix For: backlog


The vectorized executor will be implemented as a extension (located at contrib directory).

And use a GNC to enable vectorized executor, e.g:

{code}

postgres=# set vectorized_executor_enable to on;

// run the new vectorized executor

postgres=# set vectorized_executor_enable to off;

// run the original HAWQ executor


{code}
