Subject [GitHub] incubator-hawq pull request: HAWQ-273. Need re-fetch snapshot at p...

Github user liming01 commented on the pull request:

    Yes, only 2 functions:
    - _SPI_prepare_plan():  you can find that before calling pg_plan_queries(), it already
fetch a new snapshot. And between them, it just some simple code, which is impossible to lock.
So we don't need to re-fetch one.  
    - exec_parse_message(): From the comment in the code, it just called for syntax check.
    		 * Even though we do not store the plan, we want to perform planning
    		 * to know if SQL syntax is supported.
