mageUz's answer does not follow best practices for keeping your Magento installation upgrade friendly. You should avoid editing cms.xml or any of the other base xml files.

A better way to do this would be the following in local.xml

<cms_page>
    <reference name="left">
        <action method="setChild">
            <name>page_content_heading</name>
        </action>
    </reference>
    <reference name="content">
        <action method="unsetChild">
            <name>page_content_heading</name>
        </action>
    </reference>
</cms_page>

Additionally, this can be done on a per page basis by putting this XML into the "Layout Update XML" field of the Design Tab, when editing pages from the admin. You would just omit the "cms_page" node, and instead just need the two "reference" xml nodes.
