commit 18ff87e0823c960517cdc5e31d7bc7b1ee25f1c4
Author: Amit Khandekar <ami...@en...>
Date:   Tue Nov 22 10:46:13 2011 +0530

    Support correlated subqueries. Correlated subqueries were not working because
    we did not have a ReScan function for RemoteQuery plan node, and the
    Materialize plan node present above RemoteQuery cannot handle scenarios
    where the underlying node has to be rescanned in case of changed qual
    parameters.
    
    This commit :
    1. implements the ReScan function
    2. Removes the Materialize node from above the RemoteQuery node, and does the
    materialization inside RemoteQuery node.
    3. Fixes an issue of incorrect target list for remote joins with subqueries.
