> 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.
