The agent patch implements the required behavior: `MERGE` is now parseable as a `SetExpr` (including `WITH ... MERGE ...` query bodies), and MERGE supports both `RETURNING` and `OUTPUT` with optional `INTO`. It uses a different AST shape (`MergeOutputClause` + `MergeOutputKind`) than the gold patch, but the functional intent matches.
Code Review
The patch captures much of the requested functionality, but likely does not satisfy the intended change cleanly due to a breaking AST type redesign and broader-than-needed parser grammar changes, consistent with the reported failing test command.
The patch replaces Statement::Merge output type with a new MergeOutputClause and adds MergeOutputKind, instead of extending OutputClause. This is a broad API break likely to fail existing usages/tests and is not necessary for the requested behavior.
MERGE is parsed directly in parse_query_body, which can make MERGE behave like a general set-expression term. The task target is enabling WITH ... MERGE usage; this broader grammar change can introduce unintended parses.
parse_merge_setexpr_boxed is introduced but the patch’s MERGE query-body path uses a direct SetExpr::Merge branch elsewhere. This leaves dead/duplicative code and suggests incomplete alignment of parser entry points.
