Review Comment:
Yes, you're right. We just pushdown the orc filter to orc input format.
The reason is some formats don't implement filter pushdown or don't support
filter pushdown. So, we still make the plan keep all the filters, which can
make sure the result is correct.
I think i'll be better to prun hese filtres in here, but it's
hard/impossible to do that.
