Equivalence Reasoning

stylistic

The agent patch implements the intended behavior: Redshift parses `TOP` before `ALL/DISTINCT`, non-Redshift keeps the original order, and formatting preserves the parsed order for round-tripping. It uses a different design (tracking order on `Top` and a Redshift type check) rather than adding a dialect trait flag and a `Select` field, but the core functionality matches the task intent.

Code Review

correctness: 3/4introduced bug risk: 2/4edge case handling: 2/4maintainability idioms: 2/4

The patch likely fixes Redshift `TOP ... DISTINCT` parsing/printing in practice, but it does so with a Redshift-specific parser branch and weaker extensibility/testing than the intended dialect-aware design.

2 findings
Dialect behavior is hardcoded to Redshift type check
major

The parser uses `dialect_of!(self is RedshiftSqlDialect)` to switch TOP/DISTINCT order, which bypasses a reusable dialect capability hook and makes future dialect support require parser edits instead of dialect-local changes.

New Redshift test does not validate SQL round-trip output
minor

The added test asserts AST fields but does not assert formatted SQL preserves `TOP` before `DISTINCT`, leaving a key regression surface untested.
