Review Comment:
This would accept any statements that are not acceptable by Snowflake such
as `ALTER SESSION XYZ`. Suggest to rewrite as:
```rust
let set = match parser.parse_one_of_keywords(&[Keyword::SET,
Keyword::UNSET]) {
Some(Keyword::SET) => true,
Some(Keyword::UNSET) => false,
_ => return Some(parser.expected("SET or UNSET",
parser.peek_token()))
};
```
