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

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

postgres=# set vectorized_executor_enable to on;

// run the new vectorized executor

postgres=# set vectorized_executor_enable to off;

// run the original HAWQ executor
