Instead of RI's include column list why we can not think of
row_filter's columns list?  I mean like we log the old RI column can't
we make similar things for the row filter columns?  With that, we
don't have to all the columns instead we only log the columns which
are in row filter, or is this too hard to identify during write
operation?  So now the WAL logging requirement for RI and row filter
is orthogonal and if some columns are common then we can log only
once?
