Github user GodenYao commented on the pull request:

    I'm aware of grammar of external web table from GPDB.
    Here's an example:
    =# CREATE EXTERNAL WEB TABLE output (output text)
        EXECUTE 'PATH=/home/gpadmin/programs; export PATH; myprogram.sh' 
        FORMAT 'TEXT';
    However, your implementation requires creating a native table first - which is not falling
into create external web table DDL at all.
    Then user needs to run cmdline tool to **register** a new path of the file which would
swap the original paq file created by the original DDL.
