GB18030-2022 Support in PostgreSQL

Hi hackers,

I noticed that PostgreSQL currently supports GB18030 encoding based on the older GB18030-2000 standard (as seen in commits like extend GB18030 conversion). However, China has since updated its mandatory character set standard to GB18030-2022, which includes additional characters and stricter compliance requirements.GB18030-2022 is now the official standard in China, and ensuring PostgreSQL’s full compliance would be beneficial for users in Chinese-speaking regions.

I would like to ask:

Are there any plans to upgrade PostgreSQL’s GB18030 support to the 2022 version?Would the community be open to contributions in this area?

Best regards,
