Description
This pull request consolidates multiple commits on the
stable-4.2.xbranch, focusing on improving the GaussDB-Django backend, enhancing testing infrastructure, and adding support for non-root users. Key changes include initializing the GaussDB backend by adapting PostgreSQL code, refining installation scripts, updating READMEs with detailed guides, and enhancing JSON field support. The commits also address test app configurations, schema editor improvements, and CI workflow setup, ensuring robust integration with Django and Wagtail.The changes improve usability, performance, and compatibility for non-root users, streamline testing, and ensure the backend supports advanced database features like JSON fields and recursive many-to-many relationships.
