Code Review

correctness: 1/4edge case handling: 1/4introduced bug risk: 1/4maintainability idioms: 2/4

The patch partially adds TRY/CATCH tokens and parsing, but it likely does not satisfy the intended change because dialect-scoped END support and explicit END-vs-COMMIT AST semantics are missing, with at least one clear gating bug in BEGIN parsing.

4 findings
Missing dialect-level END TRY/CATCH support hook
major

The patch parses END TRY/CATCH directly but does not add/use a dedicated dialect capability (e.g., `supports_end_transaction_modifier`), so behavior is not scoped as intended.

app/src/parser/mod.rs:12824
BEGIN modifier gating is inverted for unsupported dialects
major

In `parse_begin`, when `supports_start_transaction_modifier()` is false, the code still attempts to parse TRY/CATCH, enabling unsupported syntax where it should be disabled.

app/src/parser/mod.rs:12800
AST no longer explicitly distinguishes END from COMMIT
major

The new `Statement::Commit { chain, modifier }` removes explicit END/COMMIT discrimination, forcing formatter behavior to infer statement kind from modifier presence and losing clear semantics for plain END.

app/src/ast/mod.rs:2986
Parser accepts END TRY/CATCH without dialect checks
minor

`parse_end` always calls `parse_try_catch_transaction_modifier`, increasing cross-dialect behavior drift and potential parse ambiguities.
