The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease.

@uranusjr can you check what version I should use in the migration docs(I am not sure about it)? I am just using 2.3.0 for now as one of the tests requires me to update that file.

Ah. So it turned out to be just one index missing :). Cool.

Static checks need fixing and I think this change uses an old migration head (some change likely implemented hen you branched off?)

2.3.0 should work. But yeah you should change the down_version and the corresponding column in migration-ref to 786e3737b18f instead. And fix the static check failure.
