Could we add a description what this flag does?
| ShowCharset { | ||
| is_shorthand: bool, | ||
| filter: Option<ShowStatementFilter>, | ||
| }, |

Can we switch to using a named struct syntax for this statement? See ref we're trying to move away from the anonymous struct syntax ideally.
We could have something like?
struct ShowCharSet { ... }
Statement::ShowCharSet(ShowCharSet{...})| // MySQL specific statement | ||
| // <https://dev.mysql.com/doc/refman/8.4/en/show.html#:~:text=SHOW%20%7BCHARACTER%20SET%20%7C%20CHARSET%7D%20%5Blike_or_where%5D> |

Or something similar, essentially dropping the mention of it being mysql specific, since that can change in the future or other existing dialects might also support it in some form
| // SHOW {CHARACTER SET | CHARSET} [like_or_where] | ||
| // ``` | ||
| // where: | ||
| // like_or_where: { | ||
| // LIKE 'pattern' | ||
| // | WHERE expr | ||
| // } |

| // like_or_where: { | |
| // LIKE 'pattern' | |
| // | WHERE expr | |
| // } | |
| // SHOW {CHARACTER SET | CHARSET} | |

Thinking a brief example would be enough. For detailed syntax readers can follow the documentation

Since this adds a new node to the AST, can we assert one of the scenarios that the AST looks as expected? For example
