> Currently, it seems that we look to match the ColumnInfo between the parent and the child rowschemas by calling rci = rs.getColumnInfo(tblAlias, alias) which might be a bit aggressive. i.e. we will lose opportunity to constant propogate even if the columns are the same but the alias in the rowschemas do not match.
