asyncpg does not install with python 3.12-dev

Bắt đầu với GitHub CI trace được liên kết và tệp được tạo đang bị lỗi asyncpg/pgproto/pgproto.c, tái hiện việc cài đặt bằng Python 3.12-dev. Điều tra lỗi biên dịch PyLongObject ob_digit đã được báo cáo và xác minh rằng asyncpg cài đặt thành công trên phiên bản Python đó mà không gặp build failure đã được báo cáo.

See Github CI trace

• asyncpg version: latest
• PostgreSQL version: latest
• Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
  the issue with a local PostgreSQL install?: No / Does not apply
• Python version: 3.12-dev
• Platform: Github CI
• Do you use pgbouncer?: No
• Did you install asyncpg with pip?: Just trying, it fails.
• If you built asyncpg locally, which version of Cython did you use?: 312
• Can the issue be reproduced under both asyncio and
  uvloop?: I do not know.

Python 3.12, under development, seems to have changed a structure:

      asyncpg/pgproto/pgproto.c: In function ‘__Pyx_PyInt_As_int’:
      asyncpg/pgproto/pgproto.c:40800:53: error: ‘PyLongObject’ {aka ‘struct _longobject’} has no member named ‘ob_digit’

Also, there are two repeated warnings:
