This makes me sad... but i think we need it. Lets put comments that this is temporary and may be removed in the future.

Ideally we can find a strategy that does not require any tuning -- but also need a way to unblock instances that may hit issues with page sizes etc

The backport to v9.1.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new branch
git switch --create backport-55525-to-v9.1.x origin/v9.1.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x c3ca5405cedf19e71ae644bbe62f7c1231eea3ec
# Push it to GitHub
git push --set-upstream origin backport-55525-to-v9.1.x
git switch main
# Remove the local backport branch
git branch -D backport-55525-to-v9.1.x

Then, create a pull request where the base branch is v9.1.x and the compare/head branch is backport-55525-to-v9.1.x.
