I have the similar concern with @twalthr . IIRC, currently, the casting behavior between BYTES and STRING is using base64 encoding. I agree with that there should be more encoding methods should be supported, however, it's hard to tunning the encoding methods in the CAST syntax, and this change looks like a break change? What do you think about introducing a new built-in function for this kind of conversion? Just like trino provides a set of conversion funtions: `from_hex`, `to_hex`, `from_big_endian_32`, `to_big_endian_32`, `from_ieee754_32`, `to_ieee754_32` ... https://trino.io/docs/current/functions/binary.html#hex-encoding-functions -- This is an automated message from the Apache Git Service.
