    I found from where it comes: nodeGroup.c' funcs assume that slots from
    subplan (node Sort) have ttc_shouldFree = FALSE. This was right before
    6.2 and is right for in-memory sorts, but wrong for disk ones.
    Node Mergejoin uses some tricks to deal with this - #define MarkInnerTuple...
    At the moment, I haven't time to fix this bug - will do this latter
    if no one else.
