Vadim (or anyone else), can you comment on the use of
exec_tlist_length() vs. ExecTargetListLength().  This was changed in
Mariposa by removing the first one.

The first is called only in the planner.c, and computes the length as:

    len = 0;
    foreach(tl, targetlist)
    {
        curTle = lfirst(tl);

        if (curTle->resdom != NULL)
            len++;
    }
    return len;

while ExecTargetListLength() uses:

    len = 0;
    foreach(tl, targetlist)
    {
        curTle = lfirst(tl);

        if (curTle->resdom != NULL)
            len++;
        else
            len += curTle->fjoin->fj_nNodes;
    }
    return len;

The second counts resdom as one, or add fj_nNodes.  Which is correct, or
are they used for different purposes.  Seems like the second is more
correct.
