This seems to be fixed already in beta4.  But thanks for the report!

Relevant fix is:

2005-10-19 13:31  tgl

    * src/backend/optimizer/plan/createplan.c: Fix oversight in recent
    changes to enable the 'physical tlist' optimization for subquery
    and function scan nodes: we can't just do it unconditionally, we
    still have to check whether there is any need for a whole-row Var.
    I had been thinking that these node types couldn't have any system
    columns, which is true, but that loop is also checking for attno
    zero, ie, whole-row Var.  Fix comment to not be so misleading.    Per
    test case from Richard Huxton.
