There has been plenty discussion about GB18030, and it seems we aren't likely to be able to drop that. I think there are a lot easier cases though. The easiest probably is MULE_INTERNAL - all discussions referencing it seem to be about oddities of MULE_INTERNAL, not about using it. I think it's been effectively unused since it's introduction. Due to not even having a conversion path to UTF-8 it's really not practically usable IMO. Greetings, Andres Freund
