Lili Ma commented on HAWQ-883:
------------------------------

@liuguo, may I know how you set this GUC? 

I tried to set the GUC in hawq-site.xml by adding following contents, after restart hawq, the parameter works. You can check the GUC value through "show hawq_re_memory_overcommit_max" in psql shell.

        <property>
                <name>hawq_re_memory_overcommit_max</name>
                <value>3824</value>
        </property>
