The patch implements Snowflake multi-table INSERT parsing and serialization for both unconditional (`INSERT ALL INTO ... SELECT`) and conditional (`INSERT ALL/FIRST WHEN ... THEN INTO ... [ELSE INTO ...] SELECT`) forms, including optional column lists and `VALUES` per `INTO` target. It uses a different AST design (new `Statement::InsertMulti`/`MultiInsert*` types instead of extending `Insert`), but behavior aligns with the task intent.
Code Review
The patch partially implements Snowflake multi-table INSERT syntax but likely does not satisfy the intended change due to core AST/parsing shape divergence (`InsertMulti` vs extending `Insert`) and incomplete handling of Snowflake-specific target VALUES semantics (notably DEFAULT).
The implementation introduces `Statement::InsertMulti` and returns it from parser for Snowflake multi-table syntax. This diverges from the established INSERT representation and is likely to fail compatibility/hidden tests expecting multi-table Snowflake INSERT to remain `Statement::Insert` with added fields.
The parser uses generic `parse_values` for target VALUES in multi-table INSERT. The required Snowflake grammar includes DEFAULT as a special value in target lists; this path does not add explicit DEFAULT handling and may reject valid statements like `VALUES (DEFAULT, col)`.
Adding `MultiInsert`, `MultiInsertClause`, and `MultiInsertTarget` creates a parallel INSERT representation and requires parallel support in display/spans/visitors/consumers, increasing risk of inconsistencies and missed handling compared with extending `Insert` directly.
