Enum LanguageName 

pub enum LanguageName {
    Word {
        word: Ident,
        meta: Meta,
    },
    String {
        value: Literal,
        meta: Meta,
    },
}

A routine LANGUAGE <name> operand (PostgreSQL’s NonReservedWord_or_Sconst): a bare non-reserved word or a string constant. Shared by the two positions that spell it the same way — the DoStatement DO … LANGUAGE <name> argument and the CREATE FUNCTION FunctionOption::Language clause. PostgreSQL folds both spellings to the same language name internally, but the surface form is kept distinct so it round-trips — the same NonReservedWord_or_Sconst shape as ExtensionVersion.

The string arm admits only an Sconst (a plain, E'...', U&'...', or dollar-quoted constant); a bit-string (b'...'/x'...') or national (N'...') constant is not an Sconst, so — like the code-block body — it is the syntax error PostgreSQL reports. The string spelling is a PostgreSQL surface: MySQL’s routine LANGUAGE admits only the bare word SQL (LANGUAGE 'SQL' is ER_PARSE_ERROR on mysql:8), so the parser gates the string arm on IndexAlterSyntax::routine_language_string.
