创建向量化执行引擎插件

使用向量化执行引擎之前，需要创建extension，插件创建完成之后，可以在 pg_extension 系统表中看到新增的插件条目

teledb=# CREATE EXTENSION vectorization;
CREATE EXTENSION
teledb=# select * from pg_extension;
   extname    | extowner | extnamespace | extrelocatable | extversion | extconfig | extcondition 
--------------+----------+--------------+----------------+------------+-----------+--------------
 plpgsql      |       10 |           11 | f              | 1.0        |           | 
 teledbx_core |       10 |         2200 | t              | 1.0        |           | 
 vectorization |       10 |       2200 | t             | 1.0        |           |

teledb=# \dx
