📝 Steps to edit this migration plan

1. Run the following command to pull the generated plan to your local workstation:

atlas schema plan pull --url "atlas://atlas-action/plans/pr-286-R1cGcSfo" > pr-286-R1cGcSfo.plan.hcl

2. Open pr-286-R1cGcSfo in your editor and modify it as needed. Note that the result of the plan should align
the database with the desired state. Otherwise, Atlas will report a schema drift.

3. Push the updated plan to the registry using the following command:

atlas schema plan push --pending --file pr-286-R1cGcSfo.plan.hcl

4. Re-trigger the schema/plan action to update this comment:

gh run rerun 12482128411
