The current code reassigns predicate columns from the filter to refer to the corresponding ones in the updated schema. However, it only ignores non-projected columns. `reassign_predicate_columns` builds an invalid column expression (with index `usize::MAX`) if the column is not projected in the current schema. We don't want to refer to this in the equal conditions we build. ## What changes are included in this PR? Ignores any binary expressions that reference non-existent columns in the current schema (e.g. due to unnecessary projections being removed). ## Are these changes tested? ## Are there any user-facing changes?
