## Which issue does this PR close? This further addressed the unparser issues when derived table contains match operator, `cast`, `limit`, `order`, etc. ## Rationale for this change These are common SQL patterns which doesn't work now. See test cases for details ## What changes are included in this PR? Rewrite more bits of logical plan during unparsing. The key change is to use field name to match the outer layer projection field to detect if the logical plan can be corrected for unparsing purpose, which is the reverse path of parsing for these sql during the first leg of the round trip. ## Are these changes tested? Yes ## Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
