while investing the crash, I observed that it is due to the lot of FIXME's
the code. So I just fixed minimal changes and looking into correcting
the FIXME's first.

One thing I observed is lack relation pointer is leading to crash in the
flow of EvalPlan* functions, because all ROW_MARK types doesn't
contains relation pointer.

will continue to check all FIXME fixes.
