An alternative approach is that we need to differentiate `string literal` and `varchar` like Postgres an DuckDB. Only untyped `string literal` is able to cast to any other types, so we have the *implicit casting* for query like `select ascii(42);` but not `select ascii(42::VARCHAR)` @jonathanc-n Your solution in this PR might not return error for `select ascii(42::VARCHAR)`, you might need to find a way to take `string literal` as an `unknown` or `untyped`. -- This is an automated message from the Apache Git Service.
